First of all, this looks more like a space-age piece of equipment rather than your typical sex toy. Perhaps something you would see on the space station rather than in your bedroom. It appears extremely well-made, with no obvious flaws in the engineering. The plastic tube is thick and strong, with a tight fit between it and the motor unit. Taking it apart (accomplished easily) results in easy cleaning and storage. The rubber seal makes a tight fit, but this is required for functionality. Being rechargeable is nice, meaning it can be used in bed where you are most comfortable, without having to have a long cord to tend with.

Keep in mind this is coming from a person that does not have a problem with ED. I would suspect this would work wonders for men who do, but I purchased this more as a fun thing to try rather than a necessity. Also, I didn't purchase this as something to use for masturbation, but rather as a tool to increase length and girth, as well as enjoy with a partner. The directions are clear, although doing a brief web search for hints/tips was also educational. This certainly provides plenty of suction; however, rather than feeling the suction, you feel more of a "tugging" sensation that visibly results in more length and girth. It can be visually stimulating for your partner, especially to see the before and after. The clear tube allows you to subjectively and (thanks to the markings on the side) objectively watch the size increase. I would suggest using a bit of lube on the glans and shaft, as during the expansion, the penis can get "stuck" to the sides and can be a bit uncomfortable. Easy to fix, just release the pressure valve, readjust, and reinflate. We would also recommend using a small cock ring first before slipping into the rubber gasket. This will keep things inflated without having to use the bulky gasket for activities after pumping. Once again, applying a little lube will help the rubber slide off more easily.
