The black silicone feels smooth and doesn't pinch at all, which was my main worry. I've been using the middle ring most often and it stays put without digging in.

Having three sizes in one set meant I actually found the right fit instead of guessing. The silicone has just enough stretch without feeling flimsy, and cleanup is quick.

The black silicone feels soft against skin and doesn't pull or tug, which was my main worry. Having three different diameters means I actually found one that fits right instead of guessing online.
