This black device fits onto the top of the masturbators, covering the hole where manually creating a slight vacuum sensation by covering it with a finger is usually done. It's crucial that when using the Vacuum Controller, this hole remains uncovered with the seal removed. The Vacuum Controller helps increase and regulate the vacuum, thus creating a more explosive suction sensation during masturbation, also regulating the pressure embracing the penis during penetration.

It includes a regular adapter for the Original Vacuum CUP series, Original Vacuum CUP Cool Edition, Keith Haring × TENGA Original Vacuum CUP, and an Ultra Size adapter for the U.S. Original Vacuum CUP series. It's ideal for hands-free use and very easy to control thanks to its vacuum button and pressure release button.

Requires 4 AAA batteries (not included), and the control unit is made of PC, ABS, and the adapters of ABS and elastomer.

It's very practical and the perfect complement to the Tenga masturbator series.
