Easy to install - not overly sensitive but should let you know if anyone breaks or attempts to get in. Good for the $.

Work pretty good.. give them a little bump, and they start whining. I wish they were a little louder and not so easily turned-off once the alarm becomes activated. However, they are a cheap deterrent at the very least.

This item works as advertised and is a cost efficient method to protect the windows and glass doors in your house. The only problem that I have with the unit is that it is difficult to change the batteries when they need replacement. And yes, they are sometimes triggered by thunder when there is a nearby lightining strike, but this is a minor inconvience. I live in Florida and we have a lot more storms than other parts of the country, but they have only gone off once or twice in the last six months as a result of thunder. For $13.00, a great buy! I give the product four stars, but it would be five stars if the batteries weren't so difficult to replace.

This hasn't worked since the day I got it! It will not stick to the window. Of course the window gets quite warm, but that should have been accounted for in the design

Just what we needed.

Works better than advertised. The slightest bump against a window sets the device off. They supplement our security system very well. I plan on ordering more for the rest of the windows soon.

NOT LOUD ENOUGH

Alarm volume seems less than advertised. Not as good as I was hoping. Does seem to work well in detection it is just not very loud.

We like it a lot, and we will be ordering more.

Iam very happy with the window alert from smart home. They are exactly what I was looking for, when ever Ineed things like this again, smart home will be on the top of my list. Thanks
