This pump was great! It was comfortable and easy to use in every aspect of the word. The only draw back was that the hole in the donut was pretty small, but it is made of a very smooth stretchy plastic, so it will easily stretch to 1.5 or 1.75 inches. This makes it is incredibly good at keeping the seal. The one hand finger pump worked great, the release valve is in easy reach also.

Lube was an important part of my experience with this toy. I would absolutely recommend using a water-based lube rather then oil-based with it, as it does not come apart to clean. The sleeve does kinda fold out so at least you can wash water-based lube out easily. With out lube I'm not sure i would be able to put this toy comfortably on my penis. The hole in the donut, or sleeve, is only about an inch and the tube is only about 2 inches around and 8 inches long so this toy isn't made for someone who is very well endowed; but if you are somewhere in between it works great.

My first time using this pump was quite pleasurable. It slipped on with a little lube, easily got a good suction grip on me and was really easy to use with one hand. Its clear tube lets you see how big you are getting, though if you don't find a use for your new found erection quickly you will loose it.

"One armed bandit pump|One armed bandit pump - Penis pump by Doc Johnson" may provide some more girth but nothing substantial. You can kind of use this one like a masturbator|Quality masturbators and male masturbation toys which is not a bad plus.

I feel I should warn anyone who is going to be using a pump|Man's guide to Penis Pumps that it should never be painful and serious health problems could arise from pumping too often or too much at one time. A good rule of thumb is to never have a pumping session|Penis Pump Guide: Penis Pumping Session Checklist last longer then 20-30 minutes at the most. If you ever see any discoloration, other then red, or anything out of the usual, stop immediately. This could lead to situations unfavorable to your penis and sexual health.

I noted in my first review of the One-armed bandit pump that it could be used as a masturbator|Masturbators for men. I discovered this after the first time I pumped with this toy. When I tried to remove to toy with still a significant amount of a vacuum it wouldn't budge, but if you released the pressure to a minimal amount it felt quite pleasurable. So with a large amount of lube on my member and the pump, I pumped as much as felt was comfortable. Seeing how big this toy made my cock turned me on ( the pump really works well :). I tried to remove it with out the vacuum seal broken and it stimulated me enough to get my attention. I release the pressure to only a few pumps, maybe once or twice, and stroked my shaft with the mouth of the pump. I admittedly lost control when I broke the seal by removing my cock without releasing all the pressure. Good news is the toy is pretty easy to clean :)
