Bought this in February 2018 and it's June 2018 now, stopped working overnight. Unfortunately for me I am in Europe now and don't know if I'll be able to get it replaced. Worked great when it was working and now it doesn't charge and when I plug in the cable to charge my phone through the case, it says a ridiculous amount of time until fully charged.

Ex Output:
negative


Ex Input:
I ordered this, got a cool color pink vinyl, played the b-side and it skipped several times. Well, bummer. I called amazon, got a replacement sent, same color vinyl arrived with the same skipping in the same places. Had another replacement sent. Same color, same... you get the point.

Ex Output:

negative
