Cover creaks and does not protect the bottom

Apple typically offers very good quality, but at elevated price. So I expected that also in this envelope. I bought it for the iPhone 6 in black leather and the same put into my brand new smartphone. The leather clutches his good and offers neatly maintenance. A bit of it bears on Allerding, snders It's not.
Two major criticisms I have, however:
- The cover is completely open at the bottom, not the exception as its predecessor only with the connections. Therefore, here is of course to be expected scratches.
- The casing is laterally not fit and tends to creak when using the iPhone. I buy me not a 900 smartphone and a shell 50 having to accept then creaking noise ... This is really annoying. For me, the shell is not to be used as.
