Very easy install but not as sensitive as I would like. Seems to work well for smaller rooms.

very fast delivery. the configuration was a piece of cake, until now (more than 30 days of service) none false alarms.

works well, though I was confused by the test procedure - once these units trigger, there is a reset period I was not aware of. So when I was walking around, and they would or would not catch me randomly, I was confused. Finally, I learned about the "test" setting on the base unit, and that solved my problem. So far so good.

Works great. 4 out of 5 stars because its pricey.

very good but i didnt like the fact that it takes time to reset itself

After waiting for about two months for Smarthome to ship the right item, then waiting another two weeks for them to ship it to the right address, I found the supplied battery in the item to be dead. Not a deal breaker, but still... This is an expensive item, and I expected it to work out of the box. My disappointment with Smarthome of late seems to grow exponentially. If you have the alarm system, this sensor works okay. Just don't expect to get everything you want anytime quick.

These are great motion detectors! Easy to install and allow for a flat mount or corner mount on the wall. Perfect for pet owners who worry about false alarms from pet motion, as these devices work well to exclude the motion of medium sized pets.
