Excellent and Easy to Install
This alarm system was very easy to install, and it works exactly as expected. The alarm is loud enough to alert everyone in the house if a door or window is opened. It’s a great, affordable way to add extra security without complicated wiring or professional installation. Great value for the price!

Absolute Game Changer for Our Family’s Safety
As a parent of a disabled child who sometimes wanders at night, this little device has brought us peace of mind we didn’t know was possible. The GE Personal Security Alarms are simple, affordable, and incredibly effective. We placed them on bedroom doors and windows, and now if she opens one in the middle of the night, we’re instantly alerted. The alarm is loud enough to wake us up, but not overwhelming, and the install took literally seconds—no tools, no fuss. It’s a true DIY win that doesn’t feel like a compromise on safety. Knowing we’ll be alerted immediately if our daughter tries to leave gives us a sense of control and security that we’ve been missing. Honestly, this product has changed how we sleep at night—and that’s priceless. If you're caring for someone with special needs or just want a reliable home alert system, don’t hesitate. This has made a world of difference for our family. 💜

A limited alarm that provides limited security very effectively.
---04/02/2015 UPDATE--- Amazon's stellar-as-always customer service sent me a replacement 2-pack (and paid for the return shipping for the defective pack). I've had these installed in my flat for about four months now. Four stars because "I like it", but that's because I don't expect anything that it can't deliver. Let's get real: these are rated highly because they're extremely loud and very inexpensive. They're not rated highly because they are advanced security. They're great for guarding against the kids opening something they shouldn't, and they're so-so for using as a door chime (it's much too loud to keep on all the time, but a good defense against small children wandering away). I bought them so I can truthfully tell my insurance company that I have burglar alarms installed, to get a home-security discount on my property insurance. I'll be taking them with me when I move out to another home. I'll say it again: the siren is LOUD. It will most definitely cause temporary (or permanent) hearing damage if you're exposed to it for more than a few seconds at a time. Even the chime (a loud, shrill, electronic 'ding-dong') hurts a bit if you're right under it when it sounds. Even so, if you're truly serious about protecting yourself against burglary or home invasion, then for goodness' sake, spend more than $9. With proper placement, will this startle the bejeezus out of someone breaking in? Yes, but only briefly. Anybody with half a brain will be able to locate the siren within a few seconds, and will probably notice the easily-accessed switch on the side to turn it off. That means this alarm is really only useful if A) the burglar is easily scared off, or B) there's somebody around to hear it and investigate. I knew that when I bought them, and was fine with it. They do exactly what I expect them to, and they do that limited thing very well. They were easy for me to install. I took about 10 minutes with each one, determining the best way to install it on my flat's wonky doorframes, testing tolerances and distances, and installing carefully. If you wanted to install them in 90 seconds each, though, you could easily do that. They come with custom-cut 3M Command Strip adhesive pads. Peel, stick, press, peel, stick, press, done. They use included button-cell batteries. A green LED flashes when the siren sounds to show that the unit is working correctly; it doesn't stay lit. This will probably not protect your house while you're on vacation, but it will keep your smaller children where they're supposed to be, and will likely protect your doors while you're sleeping at night. For $9, that's a pretty great deal. ---12/10/2014 ORIGINAL REVIEW--- Temporary two stars because the speaker in one of the alarms was dead right out of the package. The LED turns on just fine, but no noise gets emitted. The other unit is fine, and works quite well, but what good is a two-pack when only one works? Currently working with Amazon to get a replacement, and will update with a full review once I have a fully working package.

HUGE little GADGET... EXCELLENT CHOICE!!!!
Product Review: This tiny gadget carry’s a BIG PUNCH! Don’t let the size fool ya! It definitely gets the job done, as I have a huge place and can not hear the back garage door, open from downstairs. ITS LOUD! I love that I can turn it off & on if I need to, otherwise it’s loud enough to annoy you if the door has to open/close too much. It’s only a few days old, so I’m not quite sure about the battery life yet. Also, the photos make it look like a perfect and easy installation & it’s is! However the photos make the two pieces appear to be leveled and flush with the door/window frame. We all know doors & DOOR FRAMES aren’t flush for practicality (especially in newer homes). So your mount may not look like the AMAZON photos (realistically) BUT IT WILL WORK... If you’re like me, once you open the package, with the small two pieces & double sided tape... it’s self explanatory, THUS ENTER THE DOOR FRAME LOL. ”MY” mount is not even nor is it flush, but it works. As long as your arrows line up (on the 2 pieces) & they are clearly marked; you’re good. You have about 1/2 inch of wiggle room to make sure door opens & the magnet mount makes contact with the device mount. I had to do it 3 times because I wanted it too appear even & pleasing on the eyes. God help me LOL. Amazon Customer Service: The original order tracking was marked delivered in mailbox per my USPS carrier. However it wasn’t there. I had no idea what happened. I called Amazon. They replaced it the next day with NO HASSLE, simply on my word. To me, that’s worth mentioning! Turns out it was delivered to the model home in my subdivision. I found it & it’s on its way back to AMAZON! This was an EXCELLENT transaction! I’m pleased with the product, SUPER IMPRESSED with Amazon CS & learned my USPS carrier isn’t that bright, but I’ll give him/her time as the area is new. Thanks for reading.

Worth every dime!
Super simple installation! Batteries are installed and ready to use. And boy does this little alarm pack a punch for loudness! Wow!! I purchased this alarm for a sense of more security. I live on the ground floor of an apartment complex and transients are always walking thru the area sleeping under bushes, awnings, and for me, I had one sleeping on my patio. You can only imagine the fright I felt opening my curtains to that situation. I do have an aluminum pole in my slider door, but the alarm just gives me that added sense of security. Its on 90% of the time and my kids now know they just can't open the door without the alarm going off. ( It is placed high enough so little hands can't reach it). I feel it is quite effective and for what I paid well worth the added peace of mind. I bought the pack of 2 for just under $21, and passed the 2nd one on to my neighbor with children!

The two of the four which work, work well. :-/
This product is a little disappointing, but about what you might expect for the money. They feel like cheaply made toys and that reflects the quality of the electronics inside the units, half of which did not and do not function properly. They are small enough to use on most window frames although obviously some thought must go into exact placement. I discovered that, to avoid them being easily seen from the outside, I can place them on top of the lower half of double hung windows, completely hiding the unit from outside view (preventing the mode switch being seen from the outside). This also reduces the probability of the unit falling off (in the event of the adhesive tape's failure) because it is lying flat on top of the frame. The volume is adequate and the alarm can be heard from one end of our rather large house to the other and continues sounding until turned off at the switch or the window is closed. The chime is almost as loud and, of course, not as obnoxious and only sound for a few seconds. The reason for only 3 stars is that two of them do not function properly. They've been installed for about a week. Disappointingly, one of the four units' alarm mode failed "out-of-the-box" and another unit's alarm mode will only chirp and not continue sounding if the window is raised quickly. This creates uncertainty and a lack of confidence in the product having a long service life. We'll see and I'll try to remember to update my review after they've been in service for a while. I plan to order another package for I'm interested in whether the percentage of non-functioning units will be the same. Also, these will not readily work on most residential doors due to the offset from the frame molding to the surface of the door. A supporting block could be affixed to the door which would place the alarm unit in juxtaposition with the magnet. Some modification to decorative molding would have to also be made in order to affix the magnet securely. Having done several tests, I'm reasonably confident the ones that actually work will provide adequate warning in case of unauthorized intrusion and will adequately support our home defense strategy.

Peace of Mind
I bought these just in case we needed them for my mother who is onset dementia. I just held on to them, didn't want her to think they were because of her so didn't want to put on till had to. Few months later, in middle of night she decided to get up and put the cat, food bowls and cat box(which is a chore to move) all out on lanai for no particular reason(he doesn't ever stay out there at night). As soon as my dad told me that, I went right over with the alarms. They only turn them on when they go to bed. They are LOUD! Luckily, they haven't been set off due to my mom, my dad has forgotten about them and set them off. It gives us all peace of mind that she isn't going to stroll outside in the middle of the night and us not possibly realizing it till hours later. Installation easy, if you do set off by mistake, just shut the door instead of trying to get turned off on the alarm. Did have to hang a couple upside down to get the magnetic strips to be side by side, but not a big deal, this was due to how the door frame on a couple of doors. Plus just totally a great, easy and cheap safty item to have no matter what.

East install and good volume
Easy install and good volume. A couple of options on the sound, one which sounds like walking into the gas station for $25 on 7 but works well and easy to install and can shut off when don’t want on.

¡Perfectas!
¡Muy buen producto! Segui la recomendación de no usar solo el pegamento que viene incluido y use Kola Loka, la alarma quedó extremadamente fija a la superficie. El sonido que emiten es bueno, considerando el tamaño de la alarma
