EVA LOGIK 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

These are really great door and window alarms. Easy to install. You just need the batteries. They are really loud. Hold well to the glass window. On off button on the alarm lets you shut them off for window or glass door cleaning or for when you do not want them one. Wish I had these when our four children were home.😂. No more sneaking in or out. Good value and very good quality. Have had this product s few years ago and still do. Battery maintenance is easy and batteries last a long time or should. For a few dollars you get a lot of security.

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!

These are very loud and a great deterrent. I tested them by smacking the window. At the high sensitivity pretty much anything will set it off. At the lower sensitivity it takes more vibration to set it off, but my 7 lbs cat sets it off by just tapping the window right next to it, so it’s still very reliable. Took off a star because one of them has a broken light, it doesn’t flash, but it still works. It stopped working after the return period, which is disappointing. Luckily it’s on my highest window, so I’m not too worried about it. I would have been more annoyed if it was in the front of my house. I would still recommend it.

These are great alarms! The alarm is screaming loud, definitely enough to wake you out of a sleep. Easy to install. As far as testing it once placed on the window, I tried knocking on the widow which didn’t trigger it. But if you take a coin or a ring and lightly tap the glass the alarm goes off immediately. Something metal produces a sound more like breaking glass than a dull thud apparently. Very happy with this purchase!

They are VERY LOUD and fairly sensitive. They were very easy to install. I popped batteries in, stuck it to the window, and turned it on. I have sliding windows (side-to-side), so I put one on each side for good measure. While installing one to the other side of the window, the other went off very quickly. I don’t know if it was because of the vibration from the other pane or if it was because the curtain or something hit it… either way, it was loud and will give me peace of mind. One of them I accidentally placed in the wrong/not my preferred place (corner of the window), and when I tried to remove it, it was too difficult so I gave up. That being said, they’re very sticky! I did decide to hide the warning label and stuck that part to the sensor instead.

When on the high setting, it's super sensitive. You drop something too loud, it goes off. The pipes pop a little in the walls, it goes off. It's so loud, the sound "wobbles" thus sensitive areas are now on the low setting in case I need to reset them. These definitely work, and I feel safer knowing if anything is moving around the windows that the noise will make an intruder's ears bleed or at least will be annoying enough to jog on.

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.

Love the idea of this product, but 1 of my 8 units didn't work. No matter how I banged it around, it would not work, and it showed a quick flashing light, as if the batteries were dead. They weren't, same brand new batteries worked in other units. I want to return the whole set, but I've done that before, returned multiple items, and received another defective product again. What I are the odds I'll send 8 back, and get 8 working units in the next wet? Pretty slim in guessing, others had this problem too I guess I'll settle for having 7 that work. Wish I could return just one. They look good, the 7 that work are loud and activate when you hit them, and hopefully they deter the thieves I have been dealing with lately.

Stuck on entry level windows. Very loud! Works great.

Works great very loud

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.
