Not bad.
Indeed, it is somewhat difficult to remove but therefore it does not easily let dirt pass through.
Its plastic is a bit hard, I would prefer it softer for better shock absorption (also it wears out from hard falls).
So far it has saved me from many falls (one of them being a hard one). So it really does protect.
It is also relatively thin and does not add much bulk to the phone.
It has a super-matte finish and the phone does not slip out of your hands.
In conclusion, I recommend it, although it could be better.
