* Denotes a brand that is not unique. These models are most known by brands like June, Pixie, Bodybay, etc. As not to clutter the chart they are listed only once and will be linked to a least expensive brand. More information on all of the brands they may go buy can be found here.

Unless otherwise noted, all cups are made from medical grade silicone. Rubber cups are quite firm and TPE ((thermoplastic elastomer)) cups are safe for those with silicone allergies. Capacity is to holes when known. Please note that inclusion in this chart does not equal an endorsement.
