VicTsing Wireless Mouse for Laptop, 2.4G Portable USB Mouse Computer Mouse, Fit Hand Nicely, 5 Adjustable DPI, Page Down/Up Buttons, 20 Months Battery Life , Designed for PC, Desktop, Laptop(Black)

Had this for about a week now. Was very happy with it initially after I adjusted the dpi settings. I use the mouse all day for work and frankly, it's not cut out for that level of usage. It's already degrading in key performance categories as follows:1) Scroll wheel started stuttering and is no longer useable.2) Batteries wear out quickly. Not a big deal walking to my battery charger and popping in a new AA but doing this every couple days is a bit much.3) Mouse cursor become intermittently unresponsive but when I take it off my mousepad, it works much more consistently.Hardly worth going through the trouble of returning it for less than $11 but I am now in the market for a better mouse. My foray into wireless has been thwarted.** update 1/27/18 **The vendor sent me a new unit and I've had a much improved experience. I believe the original unit was defective. Notes:- Use a good battery. The rechargeable AA batteries I've been using are old and don't hold a charge as well as they did. A new battery resolved a lot of the twitchy cursor issues- The scroll wheel has held up well considering my high volume daily usage- I really like the size of the unit and the wired Gigabyte m6800 I went back to for a while seemed clunky in comparison- I can recommend this wireless mouse now and if you're one of the rare users like myself who gets one that's faulty, get a free replacement

UPDATE (2/14/12) By reading my original review of the VicTsing mouse you can tell that I was immensely upset with the purchase. HOWEVER - the VicTsing customer service I upon hearing my displeasure immediately reached out by email apologized for my inconvenience and offered to send me the newer version of this mouse (free of charge incl. shipping) I accepted the offer but wasnt expecting the replacement to be much of an improvement. A few days later the mouse arrived - and my first impression upon open opening the box was that they'd sent me a much more exspensive mouse to somehow compensate me - the styling, construction, (and upon reading the manual) features all were vastly improved. I connected it to my computer and saw that the problems. with the prior mouse were addressed and that in fact every operation and in every nuance the mouse was greatly improved. I've been using it for a week now and although I can't vouch for how well it will "hold up" I believe I will be pleasantly surprised.In summation - I was thoroughly impressed with the company reaction and the replacement they'd sent, however after recieving it I did think they'd sent me a more expensive model, imagine my surprise then when I saw that on the Amazon website this new mouse is LESS EXPENSIVE than the original one!I know - people will say "setttle down, it's only a mouse, and a cheap one at that " Maybe so, it is "only a mouse" - but it is a DARN good mouse and it IS a "CHEAP" one at that!Ive only had this mouse for 4 or 5 months - I don't usually leave reviews of items purchased (15 years - over 200 items) as usually I'm petty satisfied. But with this mouse I feel taken and conned. Even though it seemed to have descent features it has flaws which at first don't seem to be insurmountable as time goes by grow increasingly frustrating. The two biggest are - the 5 setting D.P.I.function which controls cursor sensitivity does not remember the level it is adjusted to between computer shutdowns. Upon restart the mouse has to be reset each time. And the other aggravation is with the scroll wheel - while upward turns of the wheel are rendered properly (most of the time) the Downward scrolling of the wheel.is sporadic at best. And the wheel also records sporadic middle clicks. Again, these problems while in themselves arent devastating as time goes by these two "difficulties".combined other minor items make the decision to purchase this mouse a bad one. I understand that this mouse is considered a "bargain mouse" but I've had plenty of experience with other mice in this category and at higher levels and expected more especially considering other reviews. It didn't cost much and know I know why.

This is a great mouse from a technical perspective. Took a chance ordering an unfamiliar brand and (it's only been 3 days) so far, so good. I have a large-ish female hand and the curve of this mouse is significantly easier on my hand than my previous smaller Logitech. I haven't explored all the options yet - there appear to be a plethora - but I do know that after popping in a battery and plugging in the wireless USB, I was using this mouse on my Windows 10 laptop within 60 seconds.I'm deducting one star because of delayed reaction time when first logging on: I unlock Windows and move my mouse and... HELLO, where's my pointer?!? I get nothing for about 2-3 seconds. I have to jiggle and click the mouse to "wake it up" and find my pointer on my screen. Maybe there's a fix for this and I haven't had time to find it, but I don't remember having this problem before. It's a wee bit frustrating, but I can live with it for now. The true test will be longevity: I can never seem to get more than 6 months out of a wireless mouse (with anywhere from 2-10 hours of use a day during the week) before it dies. If this one lasts longer, I'd probably buy again (if that delayed response thing doesn't end up driving me nuts).

This is a supplement to my earlier review concerning my original mouse which was only usable for right handers. The Company was extremely responsive to my comment, and offered to send a replacement ambidextrous version without knowing I'd already ordered one (no left handed version apparently exists). I've had the mouse about a week, and it's excellent. It's light, responsive and ergonomic (understanding it's ambidextrous). I especially like the fact that it goes to sleep fairly quickly to conserve power, though you need to know to push the small black button on the top to bring it back to life. I particularly like that the USB plug stores in the mouse itself, like higher priced mice (mouses?). You can't beat this mouse for the price. I also highly recommend this seller for their responsiveness.
