Colt vacuum pump system - penis pump by Cal Exotics - review by Jimbo Jones

Depending on who you talk to, a pump can lengthen and/or thicken an erection and can also be a means of treating erectile dysfunction issues. The Colt Vacuum Pump system by Cal Exotics is a higher end pumping device. The end user is left to their own devices, as there are no instructions to speak of included with this vacuum pump. The initial use seems pretty obvious; however, as you put your penis inside and pump the handle until the desired vacuum pressure is achieved. If your penis is not already through the entry sleeve, the vacuum will draw it in and lengthen/thicken it. It seems as though any effects are short lived; however, since as soon as the pressure is released my penis seemed to go right back to its regular size. In fact, it didn’t even really stay erect, so the treatment for erectile dysfunction is questionable in my mind as well. This is my first pump, however, so I probably haven’t found the best technique for usage at this point.

The Colt Vacuum Pump has all sorts of materials associated with it. The pump mechanism is metal with foam padding on the handles, the tubing is rubber, the cylinder is plastic, and the entry sleeve is TPR silicone. The TPR silicone entry sleeve is pretty soft and somewhat stretchy, so it is able to achieve a tight enough seal against your skin to allow for a very good vacuum. The plastic cylinder is clear, so it is very easy to see the effect the pump is having on your penis. The foam on the handles makes the pumping easy on your hands. The cylinder is smooth, but it is not intended to contact your penis, so a texture would not be very helpful there anyway. The entry sleeve has a few ridges on it, but it isn’t really meant for stroking. The ridges might be intended to stiffen the material a little.

The shape seems pretty typical for this type of device. The design feels very durable, with metal used where possible and a high quality pressure gauge used to display the vacuum pressure. The top of the cylinder has a quick release fitting so the pump and tubing can be easily disconnected. The cylinder seems adequately sized for most guys, and larger cylinders are available from the manufacturer if needed. The entry sleeve seems a little tight, but I suppose it could be altered to make the opening larger if necessary. I thought it best to keep it on the tighter side in my usage in order to help maintain a good seal.

This device doesn’t vibrate, so there are not electronic functions or controls, but the pump, valve, and gauge could be considered physical controls. The pump system works very well and the gauge has a larger range than is probably necessary, but it seems to work well at the low end. The gauge displays in both centimeters (cm Hg) and inches mercury (in Hg), so it is not in the more common psi that is used widely in the United States. 10 cm Hg is about 2 psi, and I never got over 25 cm Hg (5 psi) so it doesn’t take much pressure to see some basic results. There is a manual pressure release valve below the pressure gauge which is nice if the pump starts to become uncomfortable on your penis and needs to be removed quickly.

The TPR silicone entry sleeve limits the lube selection to water based only as anything else could deteriorate the sleeve. There isn’t really any instruction with the pump, but regular maintenance with plastic and TPR silicone is washing with soap and hot water. Conveniently, there is a quick release mechanism for the tube connected to the cylinder, so it isn’t too difficult to remove for cleaning to prevent water from getting on the pump mechanism. The tubing sections are held in place with barb fittings, so those can be pulled off as well if a deeper cleaning were necessary.

The Colt Vacuum Pump system comes in a plastic display casing that is easier to open than most. It doesn’t even require a blade to open and can be closed again after opening. It is rather large; however, it isn’t very useful for long term storage. There is a cardboard insert behind the device extolling its virtues; but, unfortunately, there really isn’t much instruction on it although there are some warnings.

Pumps had always piqued my interest. I figured it would be good to have around if I ever found myself having erectile dysfunction problems. I haven’t yet, (knock on wood) but you never know. When I was provided with the opportunity to select a more expensive item, I figured it would be a good time to get a quality pump for the future. Plus, I figured it would be fun to experiment with it now to see what it could do. I’ve used it a few different times now. The first couple of times I used it on its own and it definitely provides some temporary assistance with achieving an erection. Things look pretty big inside the cylinder (not that much bigger though), but when the vacuum is released the effect quickly dissipates.
It seems like the most effective way to use it might be in connection with a cock ring as the vacuum might help pull blood into the shaft of the penis and the cock ring might keep it from escaping. I put on my Tantus Advanced Cock Ring and after re-positioning the cylinder to allow for a good seal I was able to pump up again quickly. I experimented with pumping/holding/releasing a few times just to see if that made a difference, but it wasn’t very noticeable. I only held it for about a minute at a time; however, so I have not held the vacuum on for long periods of time. Maybe a steady vacuum for a sustained time period (10 minutes) would provide better results, but I have not had the patience for that as of yet. I’ll have to keep experimenting.
