The Tenga Flip Zero series preceded the GRAVITY series, and they come in White (gentler) and Black (firmer). The Flip Zero White has a one-way valve and intricate internal details, including an “orb” shape at the tip designed to cradle and provide targeted sensations to the tip of the penis. The Tenga Flip Zero is also available in a vibrating version (see here) to help stamina training with its extra vibrating feature.
If you want a more free-feeling stroke, the GRAVITY series allows a smoother stroke and focuses more on suction sensations.
