+ Great Design
+ Super quality
+ Has a tight fit on the device, can thus not move and may eg no sand between the shell and the smartphone.
+ Outstanding value for money
+ The volume rocker and the lock button have a good pressure point that you are easy to press.
+ Good grip in the hand. I even made my hand wet to see if this is so even when wet. Then not even slips.
-----------------------------------
No negative points.
So, the envelope gets from me a clear recommendation. My next envelope is a Pulsar Plus definitely be back.
