Produced after the Twister came out in response to needs for a big version. If lots of motion are what you like to feel then this is the toy you need. The angled ridges coupled with the 3 bulges overload you with all kinds of sensations going every which way. The principle behind the ridges is to distribute the pressure on 4 points rather than equally, thereby intensifying the feeling of motion, much like what you’d get from fingers or knuckles rubbing.
