Good leatherette, bad plastic

After a year I had to replace my phone shell, because the (white) synthetic leather of my old cell phone pocket, another manufacturer (same price range), at some point looked ugly. So I created this new purchases here in black.
after more than a month, I can say, Not so hot!
The synthetic leather and the magnet are (still) quite good and has no spots, flaws or discoloration.
Unfortunately, the plastic shell is here from to low quality and after one month some places are already chipped at the corners. Since the other providers of similar phone-book-bag had built a better bowl !!

Were both nich perhaps too much to expect the yellow of the egg, but for the price.
