I was skeptical about the finger-glove design at first, but it stays put and lets my hand move naturally instead of feeling locked in place. The combined stimulation from the wearable shape honestly surprised me.
The silicone is really soft and the finger-glove shape means my hand stays free to move however I want, which made a big difference. It fits snugly without slipping off mid-use. Honestly didn't expect something this small to work so well.
