Machine Gun automatic masturbator (gun-shaped·4 suction cups)

An automatic piston machine with a reciprocating motor built into a gun-shaped body. Measured without the attachment, the body is 25cm long, the base is 36cm x 15cm and the weight is 3.5kg. It connects through an adapter to a household supply of 110V to 240V, and the speed is set with a single knob.

Speed and stroke length

The speed runs continuously from 0 to 450 strokes per minute as you turn the knob, with no fixed steps. The stroke length is fixed at 6.5cm, so only the speed changes while the depth stays the same. Starting very slow and turning gradually gives an unbroken build rather than jumps. The output varies between DC 3V and 24V and the frequency is 50Hz to 60Hz.

Angle and the four suction feet

Two joints let you set the angle from 5 degrees down to 85 degrees up. Once you have decided the position, tighten the clamping knobs on the joints firmly so nothing shifts while the machine runs. Underneath the base are four fold-out silicone suction feet that grip a smooth wooden floor or tile. Folded away they take up less space, which also makes storage easier.

Attachments and what is in the box

The standard set is one machine, one adapter and one attachment. You choose the attachment when ordering, either the male or the female version. The dildo attachment is 20cm long and 3.5cm thick, and the cup attachment is 6.5cm x 25cm with an inner passage of 6cm x 23cm. The body comes in black and red. The supplier's warranty is 6 months, and a fault found within the first week of receipt is exchanged for a new unit.

Before you use it

The supplier itself points out several weaknesses. At high speed it is loud, and in any position where the machine is not firmly braced the body shakes and the point of contact drifts. The knobs that clamp the joints are small, slippery, thin plastic, so turning them hard with bare hands chafes your skin. The cable between the adapter and the machine is only 0.9m, so you will need a separate extension lead to place it away from the outlet. The logo is a sticker rather than paint, and the base is plywood covered in synthetic leather, so the corners dent when knocked and it rots if kept somewhere damp.
