I was actually not so lucky. I had issues with my M8 not being recognized by the computer (works fine with a iphone though. Go figure.) Tried it on 3 computers with 2 different OS's. Finally after 2 months of back and forth with Centrance Tech they told me to pay $99 and ship it back to them for repairs. :/ Still debating on what to do since it does work fine with Iphones, just not my computer.
PS. Careful about that brick charger. I accidentally missed the charging port on mine and pressed it against the Hifi-M8 aluminum chassis. Lots of sparks and the surge fried my desktop Mobo since it was hooked onto the same power strip with no surge protection. Been extremely cautious of charging the thing ever since. Don't absentmindedly plug in the charger like me or it'll go "BOOM"
