The pulse pattern caught me off guard in the best way—it's a totally different feel from the steady speeds, and the rumble is so deep it almost feels like a massage. Ring fits snugly without pinching, and the fact that it's fully waterproof means we don't have to stop the fun when things get wet. Ba
The vibration is deep and rumbly rather than buzzy, which makes a real difference. I wish the pulse mode had more variety, but the 5 speeds give plenty to work with and the ring stays put even when things get slick.
Battery hits about the advertised 30 minutes which is fine for quick sessions, though I wish it lasted a bit longer. The dual motors rumble deeply and the pulse setting is a nice change of pace when I’m not in a hurry.
