Of the 6 pieces I bought, 2 were crappie and I had to bypass the on/off switch. recommend DONT purchase. oh, and they have to be in direct sunlight for more than 8 hours to work for more than 1 hour. NOT a great product.
These things are useless. I bought eight of them and they emit so little light you can barely see anything lit. don’t waste your money on these. Wish I could return them.
