Bests & Worsts Reviews from Amazon

They passed the first test with flying colors. I left one on my southern exposure window sill for a couple of sunny days, so I presume it was fully charged. Then I left it on with the solar panel covered. After five hours it was still bright. After eight hours it was pretty dim but still put out enough light to help you find your way around a dark house during a black out, Enough to keep you from running into things or tripping over them, to read a medicine bottle label or find the fuse box and change a fuse -- though maybe not enough to tell which fuse was burned out., I charged it up again and put it in a box in a drawer to check again in a month so see well it holds its charge. I expect it well do well. ONE MONTH LATER. Took it out of the drawer and compared it with the other one which was fully charged. I couldn't really tell any difference.
