Essentially I got two of them. Obviously I don't need two cases. Amazon wouldn't let me cancel one. USPS shipping tends to be about $3 in the US. So For $6 I can send you one, with tracking number. PM me.
This one is a hard plastic back with a grippy TPU side. Doesn't interfere with using the edge. The sides are still pretty grippy, the back is more protective hard plastic rather than bendable grippy like the LUVVITT. But it does show off the back better (the LUVVITT has a matte texture so it doesn't give a wet look).
I've never had luck with screen protectors with curved screens so I don't use them.
As far as cases go, I've found Caseology cases like this one and Spigen cases like this one don't add much bulk and keep it feeling pretty thin. Anything with a kickstand is gonna feel super thick.
