Expensive, but appears to be very well made. The lights are made of aluminum, so the support is sturdier than the usual plastic. The poles are in two parts, so you have a choice of heights the light is above the surface. Battery replacements are expensive, but you should get two years or more from a battery. You have a choice of a quite bright white light or a less bright yellow light.

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.
