Quality not the best, but feel and color is good
I received a replacement for this item due to discoloration and peeling on the original one I received, but the replacement is also not perfect.  Silicone cases are usually pristine looking, but this blue one has weird cosmetic issues that are largely on the front where you're going to notice it the most.  It also does make my tslim X2 warm, but the official plastic clip case also gets warm so I'm not docking it any stars for that -- the pump simply runs warm in a pocket.
