can not understand negative reviews

First of all - the thing had me because of the price and the fact that it is the original accessories bought. When I read the reviews I have fallen even more than a few negative reviews.
1. Yes, the envelope is the top free - which is also the sense that I see it when the LED is blinking - is also so visible on the product images. On the back of the envelope covers the entire device.
2. Yes, it is not easy to pull the device out of the case. This is due to the excellent quality. I think that this will use better after some time.
3. For me, no adhesive residue are stuck in the BB logo.
4. The casing looks exactly like the pictures in the product description. Possibly is it (if the shell at other looks different) because the envelope was China dealer or ordered from a so.

I myself can only recommend the sleeve.
