LEVELZ - Bred Justerbar Silicone Lasso Cock Ring - 5mm - Turkis

The locking slider actually holds where you set it, which I didn't expect from a silicone ring. I tightened it a notch mid-session and it stayed put. The 5mm width feels substantial without digging in.

The slider actually locks where you set it, so I'm not constantly readjusting mid-session like I did with fixed-size rings. The 5mm silicone is soft enough to forget I'm wearing it, and teal was a nice change from basic black.

The silicone is soft enough that I forget I'm wearing it after a few minutes, and being able to fine-tune the tension with the slider beats guessing at a fixed size. Only gripe is that the 5mm loop can dig in a bit if I cinch it too tight, but that's on me.
