Overview

This is a manual, hand-operated model, so there is no battery, cable, app or buttons to deal with. It comes with two removable sleeves with different textures, a spiral style and a mouth-style insert, in soft stretchy TPE, so you can switch between two different feels in one compact set.

A built-in air vent lets you increase or release suction simply by covering or uncovering the hole, and you control the pace and pressure by hand. The listing also mentions an optional AI voice-chat feature that runs on your phone separately from the device, with no connection needed.
