Head massaging sleeve have become very popular in recent times. Almost all are rounded shape with different texture for stimulation. Chu! from G Project has come with their own take on the head massagers. The Chu! series has a particular bowling pin like outer shape different from others. This small area sticking out acts as a mini vacuum chamber that adds suction feeling to the head massagers. Even though vacuum chamber exist in many onaholes, this is a first for small head massagers. The vacuum chamber is also textured lined to allow you to push into this tight area for stimulation. The entrance is tight for lotion retention during use and for forming a seal to increase suction. Chu! Type 1 is the nub version with rounded nub inside for circular motion head massaging. Illustrated by ROUTE12, Chu! 1 is a great head massager.
