Review: Perfect case for the premium device - The case is as advertised. I was mainly looking for a good case which provides good grip and this one does it really well. I have been using similar but flat surfaced cases which provide good grip but this one has better pattern on the surface which provides even better grip. Worth the money!
Review: Good product, slight dust collection overtime - Cover is good quality, the edges are protected with a slight raise towards the edge without interfering with side swipe gestures,has a good grip, doesn't feel bully buttons work smoothly, camera bump is protected as well, dropped it on ice once the phone didn't get a scratch on it, will still recommend to keep a tempered glass.

### ⭐⭐⭐⭐⭐ Good product, slight dust collection overtime
*by M***I on 20 April 2021*

Cover is good quality, the edges are protected with a slight raise towards the edge without interfering with side swipe gestures,has a good grip, doesn't feel bully buttons work smoothly, camera bump is protected as well, dropped it on ice once the phone didn't get a scratch on it, will still recommend to keep a tempered glass.

### ⭐⭐⭐⭐ One of the best
*by J***E on 22 October 2025*

Amazing quality, grip and protection. Feels good to hold and protects phone from accidental drops, bumps and scratches. There is slightly raised lips to protect the display when kept face down. Overall a good investment but seems a bit expensive.
