Size Matters 7.75-Inch Automatic Penis Pump, Suction at a Glance

Let the Motor Find Its Rhythm

A clear cylinder, a soft silicone entrance and a little screen that keeps the pressure in view. The Size Matters automatic penis pump brings four continuous suction levels and three automatic patterns to your solo time, without a hand bulb to keep squeezing. Settle in, explore a gentler setting and see which rhythm catches your attention.

Inside, there’s approximately 19.7cm (7.75 inches) of usable length. Two removable silicone sleeves give you a choice of 20mm or 25mm entrance openings, while the black motor sits neatly above the clear chamber. It’s a pleasing combination of something soft against your skin and controls you can actually see.

“Let the screen keep track. You can enjoy the feeling.”

A Clear View of What You’re Choosing

The motor, display and four-button control panel sit together at the top of the cylinder. The Suction button cycles through four continuous levels; the Lips button selects the three automatic patterns. That gives you a choice between a steady pull and a changing sequence, rather than one fixed pumping sensation.

The clear chamber lets you see inside, and the pressure display gives you a visible reference as you change settings. There’s no need to chase a number: the useful setting is the one that feels comfortable to you.

Experience Level

A thoughtful choice if you’re curious about powered pumping or already enjoy suction and fancy more control over its rhythm. Start with the lowest setting, keep sessions gentle and familiarise yourself with the release control before play. Stop if you feel discomfort.

Give Your Solo Time a Different Rhythm

If you enjoy settling into a sensation and letting it change, the automatic patterns are the draw here. Try a steady setting when that’s what you fancy, or let the timed suction and pauses bring a little variety. The motor does the pumping, leaving you free to concentrate on how it feels.

Comes Apart When the Fun Is Done

The removable motor and silicone sleeves make this a practical choice when easy access for cleaning matters to you. You can separate the parts rather than trying to clean around an attached motor. The two supplied sleeve openings also let you compare the fit at the entrance before settling on your preferred one.

Care & Comfortable Pumping

Use water-based lubricant on your shaft and the sleeve entrance to help create a comfortable seal. Keep the release control within reach: press it once to pause suction, then press it again to release the pressure. Release pressure before removing the pump.

Detach the motor and sleeves after use. Wash the cylinder and sleeves with warm water and mild soap, rinse thoroughly and use toy cleaner as directed. Let everything dry completely before reassembly or storage. Charge only when the pump and charging connection are dry.

Tip: Compare the two sleeve openings before switching on. A comfortable seal is a better starting point than choosing the smallest opening.
