Great product. Works perfectly. You definitely need to read the instructions, particularly about having the gray tab side of the magnet next to the transmitter. We couldn't be happier with our unit. It was the perfect solution to a nagging problem. (We use it to tell us when the back door is open. Our kids have a tendency to open it, but not close it properly. Now we know when they leave the house ... and when they fail to actually close the door properly.)

WHEN I TALKED TO REP. I EXPLAINED THAT I NEEDED A WIRELESS ITEM. I WAS NOT EXPLAINED THAT THE SENSOR HAD TO BE CONNECTED AT ALL TIMES. NOT WHAT I NEED.

Easy to install. Works great. Reasonably priced.

very undependable highly disappointed

I bought this to have a second base station to beep in a second room when my motion detector was triggered. It works perfectly so that I can have two base stations in different rooms alert me to motion from a single motion detector. This was on sale so cheaper than buying just the base station. After a few weeks, the whole system works perfectly and was simple to install and understand the detailed instructions.

A bad product. The alarm is so annoying, I had to turn the system off. Can't it be made with a more pleasing single "ding"?

Works as described, although it didn't seem to work well on an alluminum door frame. I really need a transmitter with connections to accept an external magnetic switch.

It works for what we need it to.

By the description, I thought it would just make an initial noise when the door/window opened, but it makes a continuous noise until you close it again -- not exactly what I was looking for, but the basic function of it does work well.

I am disappointed with this product, as it never seems to work appropriately. One day it may work once, and then for the remainder of the day it does not work.
