The SUB.ONE stimulator is both powerful and ergonomic. Using tapping technology, it delivers incredible sensations and can be used with or without erection. This specificity makes the SUB.ONE an inclusive product that gives the greatest number of people access to pleasure, especially those suffering from erectile dysfunction. The SUB.ONE can also be used without lubricant, in which case no back-and-forth motion is required and all you have to do is soak up the moment. With lubricant, it's used as a new generation masturbator, where the inner texture along with each tapping movement stimulate the most sensitive erogenous areas. But its real superpower is its Pleasure assist function. It can be activated or not according to your preferences, and thanks to its integrated sensors, the tapping intensity can be increased by simply stroking the stimulator. This function, absolutely unique on the market, combined with the flexibility of its soft silicone wings, makes the product even more intuitive to use.
