Query: Cheap AC adapter

Do not buy from this merchant. They claim that this is the same adapter as factory, but this product and likely their other products are cheap knock offs. My first adapter worked for about one month and would always get very very hot and eventually blew out. I got my warrenty and the owner tried to extort me into giving me a 5 star rating if they honored their warranty policy. The second adapter was just they same, very hot and it would take forever to charge.Buyer Beware, Do not feed into their "5 star" reviews
