Glans vibrator (silicone cap·10 vibration modes)

A men's device with a cup that fits over the glans and vibrates on the inside. The cup that touches the body is made of medical grade silicone gel, soft and non toxic, while the control section you hold is ABS resin. Vibration can be changed across 10 levels.

It covers the glans only

Unlike a masturbation cup that encloses the whole shaft, this covers only the glans at the tip. The cup sits close against the glans yet flexes to follow it, so you can shift the position slightly by hand as you go. The contact area is small, which concentrates the stimulation in one place.

Two buttons and that is all

Holding the upper button for 1 second turns the power on. Each press of the lower button changes the vibration rate, and there are 10 levels in all. You can press them with your thumb without changing your grip, so there is no need to shift position partway through.

It runs on batteries

It is not rechargeable and takes two AAA batteries. You never have to wait for a charge, but you do have to swap them when they run down, so it is worth keeping spares. Take the batteries out when it will sit unused for a long time, to stop leakage from damaging the control section.

Before you use it

The stimulation is concentrated on the glans alone, so it can feel strong to anyone sensitive there. Start on a low level and work up. The control section holds batteries, so it cannot be submerged, and running water over it in the bathroom will break it. Some people use it for stamina training, but do not push through pain to keep going.
