Cheap, but not perfect

The protective sleeve is doing what was promised, it protects the iPhone on the back and on the sides.
Above and below, however, the front edges remain unprotected, which beforehand was clear, as you can see in the pictures.

Positives:
+ The shell is very thin indeed, the iPhone retains largely its slim shape.
+ It fits quite well and is easy to assemble.
+ All ports and controls are accessible without problems.

Negatives:
- The edges are not properly deburred.
- In white plastic some dark spots (discoloration) are included (I'm trying to upload a photo of it).

Optimization:
I have successfully reworked with 800 sandpaper all edges. Well nothing more scratches on the fingers or on the iPhone.

Conclusion:
A very convenient shell with smaller workmanship.
The discoloration is not beautiful, but at the low sum worth for me the return not and I accept the few points in the plastic.
