I have purchased this case. It is very inexpensive, especially considering my first charging case cost $100. I forgot my charger on vacation and used a gift shop adapter and affected the case's ability to charge. But I didn't hesitate to replace the case, as I loved it so much and it lasted over a year with no issues at all. The second case is just as awesome as the first!!!. I can charge the phone and case over night and not plug in again for over a day, sometimes two!!! I absolutely love this case and recommend it to anyone who has a cell phone!!!
