Like so many solar powered devices this one is also junk. I put it up, set it for the sun for five days and it worked for a while, never quite got to doing the job at hand on a 100' fence…turned it on this year and nothing at all. Save your money, get one that plugs into real power or uses batteries, I'd take this one back but it's been a year and I doubt that they would exchange or refund on it.
Received the energizer super fast. The set up was super easy and it's working very well. The price for this model was the lowest anywhere and it's reliability rating was good. I highly recommend this energizer for all the reasons above. Thanks Home Depot
