The rundown

This one keeps things simple. It is entirely hand-operated, so there is nothing to charge, no buttons and no app required. You decide the pace, the pressure and when to pause.

Two removable liners are included, one spiral-style and one with a mouth-style texture, both in soft, stretchy TPE. A small air vent in the case lets you raise or release suction just by covering or uncovering it. The listing also mentions an optional AI voice-chat feature that runs on your phone on its own, with no pairing to the device.
