I posted earlier that I was still waiting to recieve my unit, on the 23rd as promised. I did get it on the 24th, one day late but livable. I feared the worst from all of the other postings, but was pleased to find a sealed box, with the ipad connector which I don't need, and everything works fine. No power when opened, but after a few hours charge it showed several bars, and charged my cell phone fine. After 8 hours it was full and ready to go. I'm still using it, with no decrease in battery going by the charge indicator. If the bad units everyone has were stored in less than ideal areas, below freezing, or way above 120 degrees, that may account for the problems. If repaired they should last a long time if kept in the proper setting for storage. I will keep wooting, and try to be more patient, with them, because all in all this was a great bargain, even with the small headache I've had. Thanks Woot.
