I had some problems with the first two of these I ordered, but I contacted the D8 Superstore and they sent me replacements immediately! When my replacements came they were both the same product, however they were different boxes. One was perfect, it was amazing, felt great, the other one however (same style box as the first two) was messed up as well. (Just look for the pink box logo on the box and the triangle shaped window on the device) Overall great product as long as it’s working properly, and D8 Superstore is committed to two things. Quality, and Amazing prices. They always fix their mistakes
