The Tenga Flip Zero series preceded the GRAVITY series, and they come in White (gentler) and Black (firmer). The Flip Zero Black has a one-way valve and intricate internal details, including a series of orbs at the tip and “geared” edges near the entry point. The Tenga Flip Zero (Black) 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.
