Wasn't sure about the stretch at first but these hold a nice firm grip without pinching, and the silicone has just enough give to stay comfortable. Stayed harder noticeably longer than usual, which is exactly what I was after.

The stretch is just right—tight enough to feel secure but not so restrictive that it's uncomfortable. I’ve worn one for a longer session and it held up perfectly without slipping or pinching.

Was skeptical about the whole "stay harder" promise, but the silicone has just the right amount of give—not flimsy, not like a vice. Wore it for a solid session and honestly felt the difference in how long I lasted.
