So small, and work great. Easy enough to install by sticking them to the windows, and there is no place in my house that is out of range. I can't understand why anyone would buy any of the other sensors, when these ones are so much smaller. And batteries are only around $1 each, so when it comes time to replace them, no big deal.

I got two of these tiny sensors. They integrated into my security system without any hassle and work great. Don't forget to write down the hexadecimal serial number on the back of the units before mounting yours. I forgot and had to pull one off the wall so I could get the number (needed for integration with security system). One is about 10' from the panel and the other is 25' with walls in between and both synced up the first time.

OK, it doesn't dissapear. But is much smaller than I imagined. It is tiny. Really small. No problem to install and no operaint problems so far. If I were to need no-drill sensors for white vinyl windows, these would probably be a no-brainer in most applications.

A great product--would have been 5 out of 5 if they were a little cheaper, but for what you get, it is a good deal. It is amazing how something so small can do what it does, and without any false alarms (so far).

I just installed three of these on all my entry doors. They are so small and unobtrusive that my didn't notice them until I pointed them out. As with the other reviews, these are very thin, so go easy on them. Once installed, however, you shouldn't have to worry.

I was very surprised at the size of the sensor and magnet and was thinking theres no way this will work. Oh was I wrong! If your looking for a very small sensor that will be unoticed, then this is it. Very pleased with the product and as usual, the Technical support with programming assistance.

Based on the pictures I was expecting this to be a few inches long - the magnet is about 1 inch and the sensor about 1.5 inches - tiny! Each to setup and install, just be careful, it's so small and thin that it feels somewhat delicate.
