What I love is the sustainability of these lights. Zero batteries, 100% solar, & they last quite a long time on a solar charge. I started with one light, worked pretty great. Ample lighting, but added a second for personal taste. The pair work great. They’ve been in constant use for the last 4 months straight. One stays pretty well charged based on its position in the toilet. The other is blocked by trees, so has to be charged more often. I’d say 1-2 weeks I’ll pull one out and let it sit outside before I go to work. Get home & put it back in. Very happy with them. Just bought two more to have on hand. Very handy.Read the reviews and have had ZERO of those other issues.I’m just renting the toilet, so I found they fit nicely in the built in shelves without any hassle. Easy in, easy out. Oh, and the lady isn’t too happy the bathroom remodel is taking so long, but happy the outhouse is well illuminated.
