Bests & Worsts Reviews from Amazon

I have a longer driveway with a steep hill and a 90 degree corner. We often had visitors and deliveryman showing up on our doorstep without warning. I needed something to give us some warning that could reach up the hill, around a corner, through a garage and into the house. While this sensor may be a bit more expensive than others, the ease of installation and its performance justify the extra cost. I was able to install this quickly and easily (95%of my time was spent on setting a post to mount it on, but even with the post digging and setting, the whole thing took less than 40 minutes). The unit comes set up and ready to go. Install batteries, mount to a post or tree and you're done. You have a choice of 32 chimes to choose from and changing chimes, sensitivity and other settings is easy to accomplished. The directions are easy to follow, straightforward, and were obviously written by someone who speaks English. The diagrams are accurate, detailed and useful. I didn't need any assistance from their technical support, but it was good to see they do their own tech support from Seattle. Once installed, all I had to do was plug in the inside receiver (it has batteries too, if you don't want to plug it in) and it was functioning perfectly. I have no problems with reception, despite the distance from the house (several hundred feet) the fact that it is at the bottom of a steep hill and the signal has to pass through our garage to get to the house. It works perfectly. Now we have ample warning of vehicles or people coming up our driveway. I think I may buy another sensor and link it to this receiver so I can have a different chime when someone actually comes onto the front porch. All-in-all, I'm very satisfied with our purchase and highly recommend this to friends, family and neighbors.
