Maybe the documentation is great, but the box that I got had none, although everything seemed to be in original packaging. If you buy this and can't get them to work, you need to twist the top off the lantern. There's a bit of plastic so the batteries aren't connected, and a power switch, all behind the glass. Pull plastic, turn on switch, charge in the sun, and you should have some light when the sun goes down.I'm in Michigan, and December. Typically, they seem to be out in under 4 hours. On cloudy days, they might not last an hour with any light at all. I have put these along my drive, and it appears cars driving down the street and shining in my yard are enough to turn the ones near the end of the drive off. Even then, when the cars are away, they aren't well lit very late.Overall, they look good. Got them to mark the edge of the driveway for snow plowing. Not sure they'll survive the plowing but by then the plow should know where the drive is! What light they generate is a plus.Edit: Received several communications from the company. No help for the problems with the lights but several options to improve them. Due to customer support, overall rating improved.
