These are toys which slip over a finger, like a ring, for easy control. Finger rings are great for people who experience uncontrollable muscle spasms which could lead to dropping a vibrator mid-play. They are also beneficial if you have mobility difficulties, and would have trouble retrieving a dropped vibrator. Finger Rings are also brilliant for those who suffer from fatigue, as they tend to be relatively lightweight, and require less effort to control than other toys.
