Let's start with the basics about this pump. The plastic cylinder is 8" long with a 2.25" diameter at the base. The cylinder is slightly tapered, with the larger end to accommodate the handle. The TPR sleeve, a rather thick-based donut type, has an inner diameter of 1.25". It comes with 3 different sizes of CalExotics' "Commander Erection Enhancer" silicone rings. The business end of this pump is a small motor inside an ergonomically designed handle, which also contains the 3-"AA" batteries. The trigger is a momentary push button (finger-down, motor runs--finger-off, motor stops) inside the curve of the handle. The release valve is located on the outside/top of the handle. It also comes with a convenient case that looks much like a shaving kit bag. All the pieces separate easily enough for cleaning with the usual warm water and soap. The only piece I've really found that needed cleaning was the cylinder, due to the drying of any lube. Although billed as "travel-friendly," this is really no more or less travel friendly than most pumps. The only difference here is the nice bag that's included.

Probably the most unique piece in the package is an extension ring that attaches to the opening of the cylinder. The outside of the small is a pretty gradual concave shape. The "Enhancer Assistant" {note to self: so $7 silicone enhancers can have an assistant, but I'm still waiting? hmmm} is a a cone piece that slides into the extension.

For those wanting to maintain the results of a freshly pumped penis, this feature is awesome. No more stretching a ring to fit over the end of the pump. Attach the extension to the cylinder, slide the cone into the extension, and voila -- a little lube and you'll be able to slide the ring over and past the cone to where it'll sit nicely in the concave shape of the extension. Remove the cone, insert that which is to be pumped, and have at it!

Those with experience with manual pumps will notice immediately the difference in the process. Usually, it'll go something like: pump, grow, pause, pump, grow, pause, etc. Manually pumping lets one pump quickly (not too quickly, right gents? Don't want any burst vessels) to a stopping point or push the limits if one desires. This motorized pump is slow and gradual and once it thinks you've reached your maximum, it just passes the air through. It was a different experience, but certainly enjoyable.

I took advantage of a 30% sale to buy this higher-end toy and anxiously awaited it arrival. Upon unboxing, everything was individually wrapped and there's decent manual included. Once I connected the handle to the cylinder, I was taken aback a little by the size. It's much bigger than I had anticipated, but probably because I hadn't thought about it that closely.

After my initial use, I got really excited to write this review. A few more uses later, I had to stop myself from starting a review that would have ended up being fragmented and incomplete (not that my fabulous mentor Antipova would have let that get published...hee hee).

This pump is a TON of fun! The versatility is unmatched. The gradual pumping action is a totally different experience for regular pumpers AND removes the fears and questions that inevitably strike pumping newbies.

The donut attachment provides a traditional pump/sleeve feel. Wanna go for a little more thickness? Take the donut off, butt the cylinder against your groin and rev 'er up. If you or someone else would like to play with it while still pumped, add the extender, slip a ring over it, and get started. Once you're pumped, slide the ring off. It won't be exactly the same, but should be close enough.

The only issue I found was both the cylinder and the extender seemed a little rough along the edge. Not sure if it's a matter of my skin being more sensitive or just a detail missed in manufacturing. My resolution was to take a piece of my Venus 2000 liner. Any pump sleeve would work for this--I just recommend trimming the sleeve down, since its only goal here is to cover the edge.

I'm still a fan of this pump and use it in various configurations somewhat regularly and would recommend it to anyone with a nice coupon to use.
