Bests & Worsts Reviews from Amazon

After a couple delivery guys frightened my wife by tapping on the kitchen door at our new rural home, I knew I had to do something. So, after looking at all the options and not wishing to change batteries, I opted for this solar-powered unit. It was a few dollars more, but it seems to be a well-designed unit. And, no changing dead batteries! I had it up and running in minutes. I used the included stainless steel screws to attach it to a utility pole near our driveway. The device is pointed across the clearing of about forty feet where our driveway comes onto the property. I had to set it on high to read across that entire distance. The device is probably no more than 150 feet from the receiver, which I put out-of-sight on to of a kitchen cabinet in the house. It works perfectly. It has already detected my wife walking out the driveway to check our mailbox. It has also detected a car coming and going as well as my neighbor coming and going on his tractor. We'll see how long it holds up, but right now I am very pleased with this purchase. I am planning to buy another detector to put near my machine shed and another receiver for in my workshop. UPDATE: 9/26/19: I order another receiver to put in my shop building. The receiver in the house does a great job alerting us when someone enters the driveway out at the road. But, I also wanted to be alerted when I am out at my shop building, which is farther away. The second receiver in the shop building works great too! Again, we are very pleased!
