after a long search for a combined battery case like this, decided on this one. Have used it for one week and it has not yet failed me. It's very light (unlike many other China battery case) and the finish is just fine. It's also a lot thinner than most battery cases. It works very easy and does the job. It charges well and has no problems synching. So far a good investment.
