Bests & Worsts Reviews from Amazon

I spent hours pouring over reviews for products like this, ultimately deciding on this particular brand/model. I love the receiver- it looks nice, has nice tones, sounds good, adjustable volume, etc. The transmitter is not the prettiest thing, but I think it helps to make it not so conspicuous as well. I screwed mine to a plank and screwed that to a tree, then covered the housing with camouflage tape so it's really not that visible. It took a lot of trial and error to adjust it JUST RIGHT to get the coverage I need. My driveway is 3 cars wide, so it wasn't easy to get it right. False alarms? None. It WILL pick up the neighborhood cat, but it doesn't pick up the squirrels! And we have a lot of squirrels! There has been a few times that I didn't hear it alert and there was someone at my door, but I could have just missed it as I have it in my office and I can't always hear it if I'm in the kitchen or at the other end of the house. That's OK though, because I bought it for when I'm working in my office and need to know if someone has pulled up. The only annoying thing is when my kids' friends discovered it and kept waving their hands in front of it to "light it up" and there's been a few several minute spans where it goes off continuously because of this. Ugh. Anyway- happy with this product, glad I chose it, and time will tell how the batteries hold up. This is a 2-week review and so far so good!
