It worked great for about 6 months and then it looks like the cable was broken which made the stick not turn on anymore. We spent an hour trying each permutation and the only thing that might be an issue is the cable. Ultimately I think it's a waste of money as now that it's plugged into the mains our firestick becomes completely unusable.
