I received the Sheath in celestial blue for my 15 Pro on Saturday. The buttons are great and no c ring out of the box. I used a popsocket for part of the day yesterday and no c ring.
I now have both the Sheath and Synthesis. The Synthesis has more going on aesthetically with the camera bump design, dot matrix side grips and smooth back imo. I like the smoother/slicker overall feel and form factor of the Synthesis (the dot matrix sides which have a nice grip to them). The Synthesis is rigid AF and tough to take off, but not a deal breaker. The Sheath feels more gritty/rougher, but softer (?) than the Synthesis, if that makes sense. I can’t put my finger on the feel and grip of the Sheath.
If you could only keep one, which one? I could flip a coin, but slight edge to the Synthesis. That changes by the minute though, LOL. Thoughts?
