AIR FLOW CUP

The spiral ribs really do trap air the way they describe, and that soft pushback is the whole reason I keep reaching for this one. Suction holds up well too, even after a few uses.

Wasn't expecting the cushion-soft thing to be so noticeable, but the pushback on insertion feels springy rather than stiff. The suction holds nicely too, and cleaning between the ribs only takes a minute with warm water.

The sensation is hard to describe but the spiral ribs really do trap air instead of just feeling like solid rubber. Airy, bouncy kind of pressure that makes the insertion part feel different from anything else I've tried.
