So this is not an item I would use that often and do not own anything like it. The packaging is nice and the instructions easy to follow. Blowing it up o my take a few breaths, but can be a little tricky if you don't also Night down on the inflation nozzle to get it to fill with air. After leaving it in the sun a few minutes, it charged up enough to try and worked just as described. Would be nice to have an on/off button, instead of having to cycle through all the settings.
I left it in the sun about an hour and then it was really bright. Good product, just something I wouldn't use often.
