The black part attracts a bit more finger grease than I would like, but it's not a deal breaker.
The only real downside would be the lip height on the front, which is considerably higher than all other cases I've had, even the Spigen case for my last phone, a Samsung S7.
The cut-outs are perfect, as you would expect from Spigen, and the buttons feel natural.
Buying from MobileFun wasn't without issues though. The first case they sent to my work address never turned up, but they were happy to resend a replacement to my PO Box, which arrive quickly.
