Ring, pinch, or sleeve?
Compare the three main grip styles and the measurements that tell you how each one fits.
Ring grips
A single loop usually leaves more of the fingertip uncovered. Compare Evolved Frisky Finger, which has a fingertip well, with Neon Vibes Flirty Vibe, which uses a stretchy single loop. A photo can show the shape, but only a stated ring opening tells you its size.
Between-finger grips
Vedo Vivi and Vedo Yumi hold in place between two fingers. A stem in this position changes the angle of the device. Compare the head shape and check where the controls sit before choosing.
Finger sleeves
Evolved Helping Hand has an integrated sleeve and separate motor controls. SVAKOM Echo 2 has a removable sleeve. Compare the depth of the finger pocket separately from the overall product size.
