Extremely Overpriced
Number of Items: 4
It doesn’t hold charge too long , especially if it’s not on a perfectly bright sunny day without clouds. Even at that , It will only be able to light up for maybe two or three hours at best , and not very bright at all. Construction and materials are of good quality that’s why the one start or else zi would gave given a zero if i could. it is way overpriced for what it is. I am disappointed for what I paid and the amount of production I get from it. Would have returned it if I haven’t installed them and threw away the boxes.

Very durable and designed to last a long time
Number of Items: 2
I've had a pair of these lights for 7-8 years and would still be using them with no issues if a naughty racoon hadn't taken an interest in them and broken the glass on one of them. I was delighted to find that the identical looking ones (operate slightly differently) were still available. They are extremely simple to put together (just screw together the durable metal pieces) and turn them on to the chosen brightness. It couldn't be much simpler. I also have other Gama Sonic solar lights and they are every bit as good.

Beautiful resin lights
Size: 1 Pack, Size: 1 Pack
LOVE THESE. They turned out so beautifully on my newly sided garage. The solar power works great for someone not wanting to mess with electric. I haven’t ran into any issues with battery life. They were very easy to assemble. One of the boxes was a little roughed up and that light had some scratches on the plastic but I was too excited to hang them that I decided not to return.
