I think it’s better designed than the other battery cases out there (Lightning instead of microUSB, lack of separate elements). The quality should be fine too — I’m very please with my Apple Case. In this case the comfort of using Lightning cable, not carrying a microUSB cable, putting it on only when necessary and the rounded edges on the case far outweigh the pros of using a 6S Plus, which is always huge.
