Fleshlight Wonder Wave
The canal starts with a bell-shaped chamber that opens up to the main texture that consists of 14 raised rings spaced approximately 1/2" apart. This main canal is 0.5 inches in diameter at the rings and 0.6 inches in-between.
The texture is less intense than other Originals like the Super Ribbed and Speed Bump. It was designed to replicate the sensations of a vagina as close as possible. Therefore i recommend to combine this sleeve with the Lady orifice rather than the Mouth or Ass orifices.
The video below gives you a close look inside the Wonder Wave Insert.
The wavy design of the sleeve creates alternating pressure between the rings and the chambers while pressing in and pulling out. This continuously changing pressure is the origin of this inserts name, because it’s a wave of sensation that comes and goes at every constriction.
To get the most sensation out of the Wonder Wave, user suggested to perform long and slow strokes. Taking the cap totally off and therefore reducing the suction effect has a positive impact on the masturbation experience. With less suction the feeling of the rings sliding gently past the head of your penis gets intensified and as you slide back out you can experience the rings gripping your head.
The cleaning of the Wonder Wave is a bit more time consuming than the previous non textured models, because residues build up between the ridges. You should turn the insert inside out to clean it thoroughly.
If you are going to take advantage of the 3 for 2 deal then this is definitely one of the inserts that you should consider.
