This case is so far my favorite of several cases for my iPhone 6, which I possess. Especially I like about this envelope, that it is really very thin, and the device thus has no effect chunky. It looks very elegant and classy. Also color is very beautiful. All buttons and ports of the iPhone can easily be reached. Only criticism: The first envelope that came, had some misplaced cutout for the camera. After an e-mail request to the dealer but a replacement envelope was sent very quickly. Therefore, there is of me a strong buy recommendation.
Update on 04/01/2015: I've noticed that the envelope quite a bit thinner than the outstanding camera of the iPhone 6. The camera is thus not protected. For now 1-star deduction.
