I was planning to post some pics and full impressions when I have some more time (I'll just post pics next time). But early thoughts after a few days are -- I really like the Smartish Gripmunk a lot (I have a 16 PM BT).
Fit is very good overall. Edges are snug (a little bit of play around camera cutout but nothing overly concerning) and there's a decent sized lip on the front for lying the phone face down. Cutouts on the bottom aren't precise, just box cutouts. But they are centered and the usb-c cutout is large, and overall have nice smooth rounded edges, so great pinky comfort. Buttons are cut-outs/non-floating but feel good. Feel in the hand is excellent overall - really appreciate the types of matte cases that leave no fingerprints or smudges, and the grooved sides add to the overall grip. Magsafe magnet strength is very good too, no issues.
The camera cutout though...5/10. It takes a bit of muscle memory to get used to pressing the button when you need to, but once you have it down, using its full function (pressing and swiping) isn't a problem. I'd much rather prefer a button cover. One less ingress/scratch point and less finger gymnastics would be much preferred.
You know it's a good case when you actually enjoy holding your phone and playing around with it while it's in your hand. I love having the Gripmunk on my phone. For now it's replaced my Apple silicone. I'm not sure I can go back to the slippery feel of the Apple case, despite it having the camera button cover.
So overalll for me 8-9/10. For $20 this case is a banger. A covered camera button would make this my main, no question.
I got the black tie affair (all black) version, so I can't speak to the colored cases unfortunately.
