We've tried a few solar lights, this is definitely the best. Its a great size to fit in the bike pannier and to easily find in the tent. For us it lasted more than 4 hours at night and immediately after the sun comes up the green charging light goes on, even if you forget to put it in direct sun. I would love to have a diffuser/shade of some sort and an attachment for my bike handlebars, but I am sure we can easily rig something up.
