Well, I took the risk and bought one. So far, very happy. It has a good grip to it and they were smart enough to keep the top and top of the sides open so that I could access the buttons on my phone. I was in a bar last night and this thing was charging itself pretty well from just the bar lights. Since I wasn't using the phone, I was fully charged. Saw a guy there who ran out of juice. I gave him this thing and it completely recharged his phone in 45 minutes. So I saw it for myself and beachbomber's claim appears to actually be true. Built in light is pretty bright. So far, it's perfect for me. I wonder why they don't advertise or sell this in stores??
BabyBlip how thick is it altogether? And if you're not in a place with light, am I right in assuming you can charge the case through the USB? So in a sense you can wall charge it and THEN use light sources to charge it?
