We purchased the Peter Sucker Devil Penis Pump out of curiosity to find out for ourselves why there are so many of these products on the market. None of the pumps we looked at had anything negative to say about themselves so the only way we could get an honest assessment would be to try one out for ourselves. This pump offered several different features and was in the moderate price range so we figured it would be a good choice. This pump is waterproof, has a vibrating top, and has easy to use controls for drawing a vacuum and quick release button to release the vacuum if you get carried away when squeezing the bulb.

The pump cylinder is made out of hard plastic and has a graduated scale that measures from 0 inches/millimeters at the base to 8/20 inches/millimeters at the end of the measuring scale. This makes the pump able to be used any where in the world. One could even brag about ones length if they leave the millimeter part of the measurement out.

The base has a thick rubber sleeve that is removable which is a nice feature when cleaning. It also makes lubricating the sleeve easier when getting ready to use the pump. The pump is safe to use with either water or silicone based lubes and since the base is the only part of the pump that requires lubrication only a small amount is needed, however a small amount applied to the user does make insertion smoother. Cleaning is very simple to accomplish since the base is removable; warm water and anti-bacterial soap or any toy cleaner will work fine.

The top portion is glued in place and is where the vacuum line attaches and the vibrator is mounted. The vibrator uses two AA batteries and uses a dial type controller for turning it off/on and varying the intensity of the vibrations. The vibrator is somewhat noisy but does generate some strong vibrations. Unfortunately, the vibrations are mainly focused at the top of the pump and do not transfer down to the base of the cylinder.

The vacuum bulb is similar in design to the blood pressure cuff used at a doctor’s office. As the bulb is squeezed the base is drawn into the cylinder which acts as the seal for the vacuum to form. It also collapses against the base of the penis which allows for an accurate measurement if you use the scale on the cylinder. There is a small button that is pushed to release the vacuum and when pressed the vacuum is released quickly.

The penis pump does draw a strong vacuum and it is recommended that you should avoid this product if you bleed easily or suffer from a blood clotting disorder, diabetes, or a peripheral vascular disease. Also those who are taking any type of blood thinning or anticoagulant medication are also often told to avoid using a penis pump.

The effects of the pump; increased length and girth are noticeable when the pump is in use however it is somewhat difficult to see due to the color of the cylinder. Clear plastic would allow for the wearer to see the effects much easier. As soon as the vacuum is released the penis does return to its non-vacuum size. Penis pumps do have some potential side effects, such as chronic pain or bruising. Also the vacuum can cause some damage to the penis, which may include tissue damage so care should be used when using one. Overall, the pump worked exactly as it was described; it does increase size but only while the penis is in the vacuum of the pump. It was a good educational experience for us and now we know first hand what penis pumps actually do.

Although there was no way to measure the increase in girth, the scale indicated a half inch increase in length from the non-vacuum to vacuum length. The vibrator does not provide much stimulation and the pump does not work well as a masturbation sleeve due to the small amount of surface contact area of the base.
