Product does not work very well. You can open and shut the window without the alarm sounding.
Brought alarms at meijers with better quality.

Rated 4.0 out of 5.0 by ChrisC So far so good
I bought this for a little added security on my back door (its a 9 frame windowed door). I didn't want someone breaking the glass and just reaching in and unlocking the door. It isn't super loud, but I think it is loud enough to be a good deterrent for anyone that shouldn't be there. I have seen some other reviews that say that the alarm is triggered easily. I haven't found that to be true. I let my dog in and out of this door all day and it hasn't went off yet. I have tested though by hitting the door fairly hard and it has triggered the alarm.
Overall: I would recommend this product as a quick and easy fix.

Rated 4.0 out of 5.0 by coastdog Good value and easy installation
The product came with batteries installed, a great help. The installation was simple and the adhesive is working well even though the installation was made in 30 degree weather. The units are small and thin but they are large enough to create a security presence on your windows. They have been in place for three weeks and we only had two false alarms which I now attribute to two distant earthquakes (same time as alarms). We have had no problems with any of the units on sliding windows or doors going off while using them. Good product.
