When they're working there great. However the compartment that contains the battery and solar apparatus does not seem to be waterproof. Therefore you get corrosion inside and the unit stops working . I Opened the compartment and cleaned the terminals on the battery put it back together and it worked again. However this is a Constant problem with mine. I give up.
I have been trying for 4 days to get some light out of this item. Nothing. I believe I was sent a return as it had already been put together and the box looked as though it had been resealed with tape.
Read the instructions, I didn't first and was afraid they didn't work, all I did was turn it on and the lights are soft and do a nice job highlighting the area to be lit. Very nice and hope they will last, the Florida sun is destructive and solar usually lasts two years. So far I am very happy with them.
