I can compare the hardcover with eg Spigen Crystal Cases and Supremery must say a big praise. This cover is really crystal clear. No matter of course. But so-called crystal clear cases are often ore yellowish.
This is not case. Really clear. Very nice. The case makes an uncommonly high-quality impression. I had not yet an hardcase, which was processed so dibasic.
However, one should note that the cover, just like any Hard Case, very tightly seated and clipped one smartphone with caution and to take out again. Quick one has as a scratch brought into the frame. But this concerns all Hard Cases.
Therefore I would highly recommend this quality Case full.
