Not only will I say I am really impressed by this product, but that also it is probably the only one I have actually really been completely satisfied with. I am about 4.5 inches flaccid, and about 3 inches in girth, when this penis but goes to work.... It really works and isn't really loud either. The comfort of use is like most pumps I have used in the past, though with this particular product I will say the suction is very powerful amd effective! I have tried Bathmate X30 and other methods to improve penis circulation and girth, and must say this one really works well! Also the wife says she thinks my member is growing and she was already satisfied to begin with but she is enjoying the ride even more now as she says it's like I'm filling her up. Ha ha ha So thank you for spicing the sex life up.
As for ease of use I would highly recommend purchasing along with this product a very strong lube to apply to the tip of your member because going in is rather tight, but is great because it's almost like a cock ring when you are at full suction, and the power button can turn on and off rapidly if you like to keep the suction up to participate with what results you want.
After a handful of sessions I would suggest stopping before you see any subcutaneous redness from blood being sucked to the surface, I allow it to hold its suction seal for about 2 or 3 min and through the single session it will ever so slightly go down in suction of seal and you can turn on with press of the power button to bring up the suction and the rush of blood into your member. That being said I would also suggest giving your member a break after each session for a day or so, it's like going to the gym, never want to over work a muscle too much! It can be dangerous, though I will say that after your 1 day rest, you could do some jelqing to help with the growth and girth of your member in its process of healing. If you are unsure of that this term is there are tons of explanations on the Internet. It is a safe and healthy exercise for any male individual to practice.
