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

I bought these for my windows and doors. They have been a lifesaver. They work great and are reliable. There are a lot of break-ins where I live and these alarms have scared them away. This was one of my best purchases.

Great buy.

In General, it works fine, but one that was mounted on the window of the back door was not sensitive. The battery can last over a year. We are sure that the continuously flashing light will scare someone.

Install all six easily. I like the flashing LED as it will alert me when the batteries need replaced.

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 like everything about this item, it is everything as described. But I do have one thing to say...My house is very discrete, I'm in the middle of my block, and I'm a single story with two story houses on both sides. I put these on all of my windows, and they are great, just as advertised, but after installation, looking at my house from the street at night, the blinking red lights were a serious eye-catcher.I don't like that, I like to be the house that does not stand out, I want to be in the background. The blinking red lights made my house stand out like a swore thumb. I see no other blinking lights in my neighborhood so I opted not to use them on the front of my house. I think they will attract attention instead of detouring attention. I do have them on all of my other windows though (every window not facing the street, I figure that if someone is willing to come into my backyard or side-yard, this product will be a significant deterrent.

After recent neighborhood break-ins and not being able to afford a full home security service, I gave these a try on our windows at street level. Wasn't too sure this would deter anyone and then I accidentally bumped the shade against the window while cleaning. HOLY COW!!! Is that loud. Scared the bejesus out of the entire household and my kids never get out of bed for anything!! Yup. They work. The little blinking light is also a deterrent, at least its a warning. Highly recommend!!

I would have to give half and half satisfaction. On a positive note they are super loud, easy to install, batteries are easy to replace. I also had a few work at different times.. The down side is that they’re not all trustworthy. For example I woke up one morning and one had fallen off the door but never alarmed. I would think that falling from 4 foot in the air and hitting the floor should cause a vibration alarm to sound but it did not. Had a few more that didn’t sound with doors being slammed or the window being hit by a basketball. I also don’t like the fact that the light is on the side so standing at the road I have half a dozen red lights blinking from every window that I can see from the road. And that could be a good thing if someone wants it to be seen but I don’t like that it draws that much attention to my house with all the blinking red lights
