The Roadster has a stronger grip on the shaft and testicles thanks to thin, but limited loops. The vibrating head has a wide, slender profile with one-touch power on the rear center.
The Roadster is a double vibrating ring, each with two loops, one to secure and stimulate the shaft, and the other for the testicles.
