My wife had pointed these out before our camp trip. We had the chance to play with a couple sets of these for a 4-day trip. Charged them up before heading out so that Solar was to replenish what we used the night before. On the lowest setting we just left them on all night long and into the morning. They worked great. Added great ambiance to the campground. ONLY thing I wished these had was a photocell or another way to automatically turn off the lights when daylight was present. If you forgot to turn off the lights in the morning you could unnecessarily drain your batteries. One of the features I really like is the fact that you can wind and stow the lights in itself. Makes for transportation and organization perfectly managable. Would recommend this... but dang that photocell would be the tops.
