From what I remember with the OB Symmetry back in the day, the hard plastic back was kinda slippery. I haven’t seen this latest iteration. Is that no longer the case? (Haha see what I did there)
It does have a very light texture but it is smooth, I can't see anyway of holding the case without gripping some of the rubber sides too, unless you balance it on the back with your finger tips lol.
I like the smooth back when holding it and i am picky when comes to a slippery case, i returned a UAG pathfinder that was like a bar of soap all around.
I have a 11 pro, so maybe the Max would be not as good/worse.
Thinking about it the size of the max with the case maybe a problem slippery wise.
Set up a friends max over xmas they got a Incipio DualPro case, had a nice feel/grip to it, has a big lip without a GSP, looks like it could be a fingerprint magnet.
Counted it out for me.
