Bests & Worsts Reviews from Amazon

This product is a scam. It's an endless cycle of waiting for it to fail, climb back up your ladder, and take it down. I've bought 8 total of these and sent back 4 - or so it seems. All the up and down on the ladder may have my memory skewed. The scam is that about 3 weeks into it you decide that it's time to trash the box. You can't return just one, so you have to buy a new set, take one that may work out, replace it with your broken one and prey that the new one works. If you don't walk you property to test them each night, it's likely that 50% are failed already. It's really a clever scan keeping money flowing between supplier, amazon, shipper, return office and repeat. Everyone makes money off of your back, climbing ladders and risking your life. Let me tell you, when you walk your property and another has failed, you will consider just giving up. I'm sure that's another portion of profits. When they work, they work well - for a few weeks.
