R.A.T. 8+ Adjustable Wired Gaming Mouse - 16000 DPI - 11 Programmable Buttons - 4 User Profiles Stored Directly - Customize RGB LED - Additional Palm Rests and Pinky Supports - Black

My last mouse was a Steel Series Rival 500. Steel Series has decided to turn their drivers into a massive marketing portal. You have to create an account on their website and "Log Into" Steel Series in order to use their drivers. Plus they started injecting advertisements onto the desktop. Yeah. Ergo, I am ejecting Steel Series out of my PC. See yah. I found this Mad Catz mouse and it seems to be wide enough (skinny mice give me cramps) and have enough buttons for me, so I ordered it. I'm so sad I didn't upgrade to this mouse long ago. First really really really cool thing about this mouse, is that it doesn't use any special drivers. You read that right. It's automatically seen as a standard HID device by windows. It's hidden super power is that it carries it's configuration and processing on-board the mouse. Not on your PC. Meaning if you moved this to another PC or other device, it will still behave exactly the same. So how it pulls off this trick; It has four profile memory slots. They are: Black, Red, Blue, and purple. There is a dedicated (unmappable) button to toggle through the four profiles. You don't have to use all four profiles if you don't need them. But you can. This is where your configurations live, on the mouse itself. The software that comes with this (download from Mad Catz) is a configuration editor. Now it takes a bit to wrap your head around this, and there are no instructions or help files. *sigh* But here's how it works. The editor has (unlimited?) profiles that you can create or edit. When you get it how you want, you choose which mouse profile you want to "apply" to (Black, Red, Blue, Purple). I find it works best if you manually put the mouse into the profile mode (example "Red"), then create a profile named "Red" in the editor, and apply it to the second slot with the editor. It's sorta janky and it's not explained that the editor itself has profiles, and the mouse has slots, and you can flash any profile to any memory slot on the mouse. It's a little buggy, but once you get it and grasp the concept, the power behind it becomes apparent. The downside of flashing a mouse with a config (or set of configs) is that there is no software running on your PC to auto-select a profile when you boot up a particular game. I have two profiles I use, one for desktop (Black) and one for gaming (Red), my blue and purple profiles aren't used yet. I might find a game someday that need a radically different setup, and I'll use the blue or purple. I won't delve into all the settings and macros you can create and so forth. You can do pretty much any setup that any modern mouse can do. DPI settings, remap buttons, setup a sniping button, assign key combos. It's all there. This is it. The Holy Grail of gaming mice. Better than my old Logitech G700s, better than my Steel Series Rival 500. You can change the weight, the length, the grippiness, it comes with a slew of replaceable grip panels and has a wrench for adjustments built right into the rear. I mean seriously, how has this mouse not set the gaming world on fire? I can only speculate that the lack of documentation means some users can't get a good grasp on it's configuration. The separation of editor with it's profiles and the flashable memory slots on the mouse itself is never explained anywhere. Finally, I've read where someone claimed the mouse had lag, but I've measured it to less than .006 seconds, and since human response time runs around .200 seconds, this isn't factor at all. It's as fast or faster than any mouse I've ever seen. So there you go. That's it. I love this mouse. It's has features no other mouse has, and for less than $100, it's a total steal.

ABSOLUTELY AMAZING 11/10!!! I have owned and used this mouse for a little over a month now and I cannot stress enough, this mouse is AMAZING. Don't like the side rests? Change it. Don't like the weight? Change it. Don't like the LEDs? Change it. Don't like the palm rest height? Change it. See the pattern? Everything about this mouse is absolutely, 100%, customizable which makes its ergonomics second to none as you can form it to fit your hand no matter how big or small your hands may be. This mouse is one of the heavier mice available, second only to the ASUS Spatha, personally, I think this is a major plus as I came from the old Logitech wireless mice that took AA batteries years ago. If you do not like that weight though, you can remove weights from the mouse to give it a lighter feel. The DPI selection buttons on this mouse are one of the best designs I have seen on a high-end gaming mouse, bare in mind, I have used them all. The Logitechs, the ASUS Spatha, the Corsair's, the Razer's, even some off the wall names that make customizable mice, this R.A.T 8+ mouse is absolutely the best of all of them. The customization is second to none, the materials are absolutely the highest quality that I have ever felt in my hand. The ability to change all of the laser's settings makes lift-off height a non-issue. The clicks are satisfying and the, "Sniper," button on the left thumb rest is extremely useful and very well placed. The details on this mouse also set it apart from the competition and add a very cool look to it. The reinforced metal body of the mouse also provides confidence that I could throw this thing across the room and into the wall and full force and there not be a scratch on it, it is absolutely RAGE PROOF. It also comes with an alan key built into the back end of the mouse in order to change out the pieces quickly and easily which is probably my favorite feature. The software is also very easy to use and allows you to customize each individual LED light and make sure that they are the colors that you want and also offers some cool lighting modes. In summary, I LOVE THIS AMAZING MOUSE AND RECOMMEND IT OVER EVERYTHING OUT THERE 15/10 WOULD BUY AGAIN!

The RAT series of mice have long been my go-to. They are the only ones that fit comfortably in my (rather large) hands. It's the most adjustable mouse on the market & perfect if you can't find a gaming mouse that's comfortable. I love the weights as well, I like a heavy mouse & I added extra weights from my old mouse. The thumb & pinky rests are a game-changer, it's so nice not to be dragging your fingers along while playing. The side-scroll wheel has become indispensable to me. I use it as a volume wheel & having that functionality literally at my fingertips is amazing. The RAT 8+ feels higher quality in basically every way compared to the 7. All the buttons & scroll wheels feel good, the rubberization is so nice on the hand, all the interchangeable parts attach completely solidly. It's a bit on the pricey side, but at least in my case this is the last mouse I'll ever buy, and since the quality is there I have no complaints.

I am a big fan of modular things. I also have a hard time finding a computer mouse that doesn't irritate my hands. Enter this thing. It comes with lots of pieces so you can mix and match to build the best mouse for you. The built-in tool screws into the back so you always have what you need to take it apart and make adjustments. I constantly use both scroll wheels, so I was very excited to see that this has two. It's been easy to use and was immediately more comfortable than the mouse I'd been using. The software is also easy to use, allowing you to program the buttons to keystrokes, macros, or common commands. I've got five of them set to various shortcuts for the program I use most often, and it's made my work much faster for it. I find that only very rarely do I need my keyboard. My hands are pretty big and I found that even the largest pinky rest was too small for me. Fortunately, I have a 3d printer and was able to make my own piece to fit to the mouse and extend that out a little more. It's been much more comfortable since, and I wish all computer mice were this modular.

Using it for a couple weesk now. Definitely the most unique looking mouse I have owned. Took a couple days to get used to it, and it used to me. Its is surprisingly comfortable now... so long as my arm is supported . I frequently use the mouse without my chair armrest (which is unfortunately at the same height as my desk, occasionally hitting it when lowered). As such, I have quickly found this mouse to operate on the principles of levers. You extend it out all the way for your large hand, put your wrist on the back, and it flings up like a catapult. While the top adjust for your larger hands, the bottom that make contact with the surface is static, optimized for small to medium hands only. Otherwise, its mostly been a pleasure. I use a tiling window manager, and have the thumb scroll set to volume, and win+thumb scroll to change workspace/virtual desktops. win+middle to play/pause, and win+forward/back to next/prev track. My keyboard has dedicated media controls. I do not use them. They are too far away, and the mouse is too convenient. Only issue I have is there is no programming software for it on linux. This doesn't bother me much though since it still functions as it should (drivers are fine, registers as a mouse and keyboard), and I can just map the keys myself like I always do, in a proper language instead of some cheap gui. Though its too bad I cannot change the keycodes sent, control dpi, or alter the leds via software. Even if I remap keys in on the computer anyways, I cannot remap a button that doesn't send a keycode to begin with (eg. dpi buttons) so had to use a windows computer to change that. Not positive I would say its worth the cost. If you do not know what you want in a mouse, this can help you confirm 1) If you want a medium or large one 2) How wide you want it 3) Rough weight 4) Max needed sensitivity (its highest setting will take you from screen1 to 6 without lifting your wrist, faster than anyone needs) 5) How useful a thumb scroll is to you (I prefer it for volume, though extra buttons are acceptable as well) 6) What a pinky rest is, and whether or not it is right for you. This is definitely better than your average cheap mouse by a longshot. That said, if you know what size mouse you want, there are several much cheaper, less configurable mice with more lights, buttons, bells and whistles on them that function as well or better than this. The true selling points here are its uniqueness, and adaptability. Which means after the first week of finding out your preferences, you may find yourself debating if its uniqueness is worth paying $30+ more than a mouse made to your preferences to begin with.

I used to use the Saitec Cyborg R.A.T. mice and was very happy with them except that they needed an explicit X config (in some /etc/X11/xorg.conf.d/*.conf file with a 「Section "InputClass"」) to tweak one button that didn't generate an "up" event IIRC, and the mouse wheels on most of them would *eventually* start glitching with extra or missing rotation events. In contrast the R.A.T. 8+ I have now did NOT require any special config and is instead picked up immediately by X (log line: "config/udev: Adding input device Mad Catz Global MADCATZ R.A.T. 8+ gaming mouse"). I haven't had them long enough to judge mouse rotation longevity yet, but if that one past issue has been solved then this mouse or near variations will probably be the only kind I buy for many years to come. The horizontal scroll wheel is quite nice in webpages and so on, although I've added multiplier to make it quicker in Firefox, in about:config mousewheel.system_scroll_override.* --- If anyone still has one of the older ones, or one of these isn't recognized, the config stanzas resemble this, where 0 is disabling a button. Section "InputClass" Identifier "rat9" # "Saitec Cyborg R.A.T.9" MatchUSBID "06a3:0cfa" Driver "evdev" Option "Buttons" "17" Option "ButtonMapping" "1 2 3 4 5 0 0 8 9 7 6 12 0 0 0 16 17" Option "AutoReleaseButtons" "13 14 15" Option "ZAxisMapping" "4 5 6 7" EndSection

So lets begin by saying that I have been a big fan of the side scrolling wheel. It adds a new level of control for PC games and even some creativity software like adobe photoshop. However, I've encountered one serious issue with this mouse. keep reading for a full review and personal experience. Lets begin with construction. Its sturdy and well made. The fact that you can switch parts (which are included) is an amazing touch that I wish other companies would get on board. The terminator look is second to none and its ability to adapt is unparalleled but not everything is perfect. I like gripping my mouse like a claw. Which means I have an arch on my hand when gripping the mouse, this mouse is fairly flat which makes it a little uncomfortable. This is however subjective so it may not apply to you. The button configuration is so-so, I dont like the size of the sniper button (if you don't know by now, this button dramatically reduces the sensitivity of the mouse while you hold it down), its so small that it feels like you have a pebble on the middle of your thumb. Had it been rounder and wider it would have been much better, without a doubt. The other side buttons are very flat and thin, slit-like (mouse button 4 and 5). They are serviceable and not terrible but again, I wish they felt more ergonomic to the hand. All buttons however, do provide a very clear and concise feedback when you click them. I did in fact like that, but I wish the buttons were better shaped and sized. Im no designer but it could have been better, 100%. Alright lets get to the point now. The clicks, though very flat sounding with immediate feedback and low travel sometimes do not register as well as the buttons. I cannot figure out why but it was costing alot of losses in popular titles such as Warzone and Warhammer Space Marine 2. At first, I thought it was me not reacting quickly and with the regular level of dexterity and accuracy. But I was wrong. It was the mouse, proven after I switched back to my older Razer mouse (the excellent Basilisk 3). I was dominating again, my reflexes were good and I was back at 1st place on the leaderboard. Clearly, it was the mouse. Rat 8+ at its high price tag is absolute garbage. It does not provide the proper value for the money. I cannot stress that enough. I suspect its a quality control issue (software) that cannot be remedied by tinkering with it. It saddens me that I paid so much for such substandard product. It fails at its most basic function. Now, you may say that I have a lemon. I simply got unlucky and got a pretty bad one out of the factory. Perhaps, but this isnt my first MadCatz R.A.T. mouse. My previous one also suffered a similar fate.. but towards the end of its life. Same delayed reaction problems or no reactions at all. I wanted a new one simply because I felt that the side scrolling wheel was a game changer. Perhaps when someone comes up with a better one for gaming.. but as of right now I cannot recommend this pile of... *ahem*. Skip!

Have been using this brand for over a decade. It is a HEAVY, precise mouse that does not jitter around the mousepad because of your wrist pulse is moving it. THIS MODEL ALSO INCLUDES ALL THE RIGHT SIDE PINKY RESTS AND CHANGEABLE PALM RESTS AS THE +8ADV!! Unlike FAR too many mice (Cosair) you don't need professional setup experience to use the key mapping or any other software, which does not interfere with my Razer keyboard OR keypad! I like the weight adjust and lead screw left thumbpad adjust as well as the palm rest fore and aft adjust, with replaceable palm rests for more height. Have a person with a large hand and another with a small hand both using their own zeroed in mouse physical and software settings with great performance for both! The only other mouse in the 'Adult' weight class I've ever used was a Razer Ouroboros, But Razer went Flimsey like Logitech, so I've parted with those brands. I'm just glad somone resurrected this brand!!

Tengo el RATT 7 desde hace más de 5 años y sigue perfecto, así que me decidí a comprar una versión más nueva, el RATT 8 para otra PC. En diseño es idéntico, con la adición de luces RGB y software actualizado. PROS: El diseño ergonómico, personalizable, fácil de instalar, software x64 y x86, CONTRAS: Algunas piezas que antes eran de metal ahora son de plástico, incluye solo 3 (antes eran 5) compensadores de peso adicionales,

Ergonomi canavarı bu mouse hep istemiştim Amazon un yurtdışı alım imkanları sayesinde nasip oldu. İlk bir yadırgadım sonra bağımlısı oldum. Serçe parmak çıkıntılı takımla kullanıyorum mousepad e sürtmemesi parmğın benim için iyi artı. Yazılımı sorunsuz ve tüm tuşlar özelleştirilebilir durumda sana her türlü ergonomik imkanı verdiğinden ah elime oturmadı diyeceğin bir duruma düşmüyorsun. Ses halkası olması üzerinde gerçekten en büyük ve pratikleştiren ayrıcalıklarından biri. Alt bölümü metal üst bölümü sert plastik. Eski sözde pahalı ve meşhur markadan olan mouse um çok seri şekilde aşınmıştı bunu ise 6 aydır kullanıyorum hala ilk günki gibi. Oyundan ziyade video kurgu için kullanıyorum ve gerekli hassasiyeti bana sunduğu için ayriyeten mutluyum.

My last two mice were both R.A.T. 7 variants, the original and later Contagion. Both served me well through their years of use, with the Contagion holding up for at least 7 years and now showing a fair bit of wear. I liked them so much, it was only natural for me to want another after my Contagion's clicker finally started failing. At first glance, the 8-Plus just a 7 with RGB, cause it basically is. It also has 2.5x the dpi of the Contagion. Quality wise, it looks to be similar quality but feels only marginally cheaper. It also comes with only 3 weights instead of 5 and doesn't even include the weight cartridge or accessory case. In actual use though, it feels very similar to my old Contagion. On board profiles are definitely a nice change over having to run the app and manually activate my profile every boot, now you only have to launch the profile manager when you want to change something. But that 16000dpi... I found it completely unusable to the point it was hilarious. I'll stick with 5000 for desktop use with reduced in-game settings. If you like the old R.A.T. 7, this is as close as you'll get without finding old stock. We'll see how it holds up, but for now it's certainly a competitor for my favourite mouse.

I have used Mad Catz R.A.T. Mice for years. I have tried other good quality gaming mice but my R.A.T. Is the best. Love it with all my PC gaming heart.

This mouse was as good as the old rat 9 i had many years ago, but better.After retiring the old mouse (only reason is that is had no RGB) i tried many top end mouses,(Corsair,Rog Spatha)but i was never really happy.When i saw it was available again i purchased it.Will not let go this time.
