- Modern Ultra-Thin Window Alarm with Loud 120dB Sound and Vibration Sensors Compatible with Virtually Any Window, Glass Break Alarm Perfect for Home, Office, Dorm Room- 8 Pack

The EVA LOGIK Modern Ultra-Thin Window Alarm is a fantastic security option for peace of mind at home! The 120dB sound is incredibly loud and definitely gets your attention, while the vibration sensors add an extra layer of security by detecting any impact or tampering with the window. It’s super easy to install, and the thin design makes it blend in seamlessly without being intrusive. I love how effective it is in providing an extra layer of protection without the need for complex installation. Whether you're at home or away, it’s reassuring to know that this alarm will alert you instantly if there’s any unusual activity. For a simple, reliable, and budget-friendly window security solution, this is an excellent choice!

Great product. I put them on all my glass doors and windows. They take AAA batteries and have a little light on the top that blinks red every 5 seconds or so. While I'm not going to break any glass to test efficacy, I did however pound on the glass of my door near where I placed the product, and it went off! So if someone was trying to break in, even if they weren't successful breaking the window, the product will go off. And it is LOUD! I live in a 3500+ sqft home and I can hear it upstairs in my bedroom with my door closed, air conditioner and air filter on. I highly recommend for anyone who wants to feel more secure in their home. Also, the way it adheres to the window is with a sticker that makes it clear it's a security measure. I'm definitely going to order more because the pack of 8 didn't cover every window/glass door on my first floor.

These little window vibration sensors work very good. They are extremely easy to install and you can adjust the sensitivity from very sensitive to relatively sensitive. I quail flew directly into my window and set the alarm off. Since I have a lot of birds, especially quail, around my house, they are constantly trying to fly through the house rather than flying around my house. All I had to do was to decrease the sensitivity level and that problem was solved. Theses vibration sensors are made of tough material. They take three AAA batteries, (so keep extra batteries on hand), and I can't tell you anything about the battery life yet but they are still going strong after about three months of use. I would imagine they are good for about a year or more on just one set of batteries. With robberies on the rise EVERYWHERE these sensors just give you added peace of mind that your windows will be just one less area of your house you need to worry about as being an entry point by the bad guys. Off subject: I would also recommend motion detection alarms placed in strategic areas around your home to alert you of anyone approaching your home before they even pull into your driveway, climb an exterior fence, etc. The one I like the best and that works flawlessly are the "Guardline" motion alarms (Can be bought on Amazon as well). Yep, they are a bit more expensive than some of the others and do take a little more set-up than many of the others but the set-up process allows you to customize the motion detecting features to exactly what you want, not to what the factory wants or thinks your setting should be. You know folks, Amazon should reimburse people for doing "all" of their advertising, and much of their technical support for them, (Do not attempt to use the Amazon Customer Service to find out how to operate, assemble, or problem solve a product you just bought). The only way you can get answers for anything other than your membership or returns is to go to the reviews section). These reviews are scrutinized by many people before they buy a product from Amazon and in many cases items are bought from Amazon based solely on these reviews. I am very tired of selling products for Amazon, or answering technical questions that customers ask about a product without being paid for this extremely valuable aspect of their sales strategy. You Tube pays customers a great deal if they have a successful video, and I mean a lot of money, Very good reward system from You Tube. Come on Amazon, start doing what is right and stop using customers to make a lot of money without reimbursing them for their help.

Exactly what I ordered 👍🏾

I think these are a great solution for a low-price security improvement/hack. They are SCREAMING loud and easy to install. I love the blinking light and sticker so any would-be intruders see they are there, and I know the batteries are still working. They have a setting for light or higher sensitivity. I have them on the lower sensitivity and when I tap them they squeal, so I keep them there to avoid going off on windy days. If you clean the glass with window cleaner and let it dry before you stick them on, they will stick better. BEFORE YOU PUT THE STICKER THE BACK- Pay attention to where you want the on/off switch, as well the blinking light indicator. After I put the sticker on the first one, I realized that I had limited placement, unless I wanted the writing to be upside-down/sideways. It's circular, so not a big deal, but now that one has the on/off switch and blinking light down low where it's not as easy for me to see and turn off if/when it's sounding on accident. Also, make sure you stick them where you want them: once on I couldn't pull them off to re-stick without ruining the sticker. I suspect I'll need to use something like WD-40 to get them off.

I purchased 4 pk and one of 4 was not shutting off. I contacted customer service and I must say that they offer top notch customer service. Which is very rare in today's world. They replaced the unit within days and gave me options on whether would like credit or replacement. Unit's offer extra security and peace of mind. I would recommend this brand to anyone interested in this type of security.

Works great very loud

I haven’t actually used them yet but they do work I tested a couple out the box and they work so should be fine

Product worked as advertised but was not sensitive enough when disturbed. Unless you really bang the glass hard or hit the unit hard there will be NO response.

The two sensitivity settings seem to work reasonably well and don't give unexpected nuisances for bumping, opening closing window, or opening closing garage door. I like the little flashing red LED. Not annoyingly bright or anything but would catch someone's attention at night and I would hope it's a deterrent before someone would try breaking in. When the alarm goes off it's fairly noisy screechy in that room, but the sound doesn't carry so well very far and upstairs if you were a heavy sleeper you could easily miss it. Not sure if neighbors would notice it or not. Definitely good enough tho to really spook someone who's right there when it goes off. Big issue is the sensor thats on my window that gets the full high afternoon sun will go off when it's an especially hot bright sunny day. Other three sensors in indirect sun or shade haven't done this. When it's nuisance alarming from the heat if I switch it down to less sensitive setting from higher sensitivity it was on then it stops alarming. Switch it back up it alarms. Switch it down it stops. I've now left it on low sensitivity for this window all the time, no issues yet but haven't been home while it's been hot and sunny either. Hopefully it's fine. Some ppl complained about the sticker that holds on the sensor to window that has a kinda lame warning logo that you'll see thru the glass. Looks kinda dumb plus it's also clearly an unmonitored brand. Sticker is double sided tho so I just put blank side facing out. Simple. Now you can't tell if it's a wifi switch or cheaper unmonitored. Not sure how long the batteries will last but it's been installed a few months now and still working so worst case you won't have to change them that often. Not exceptional value but not crazy expensive either. Satisfied with purchase so far.

these work great, and good price too! After 3 years none of the original 8 are working.
