I've been looking into this thing also becasue I really wanted one mostly for the convience of them but the guy at VZW showed me the pad. It's only as big as the phone so you can't charge multiple devices on one and it costs about $69.99 just for the pad. So the battery cover is $39.99 and the charging pad is $69.99. So I would pay approximately $110 each for three of these if everyone in my family wanted it. The guy also said it is only for the stock battery and the cover itself is designed to do the charging and doesn't require a different type of battery. I will be getting an extended battery for around $7 (25% discount + $30 VZW gift card) and then just get a case for it.
