pain to use. when i first plugged it in, it worked fine. but a few hours later i unplugged the power and usb cable, replugged them in, it's not working. My keylight that charges through usb has charging light come on, but when i plug my iphone usb cable, it doesn't charge or sync. tried different cables and devices, they still don't sync or charge. i visited their website, and shocked to find "Bandwidth Limit Exceeded". Bandwidth?? they must be using free webhosting account for hosting or something.
