Pretty nice vac tube

I like that I can pump with warm water in the tube. As one of my daily pumps this seems to really deliver results.

Not what I expected

Initially I didn't buy this because I was looking for a big penis, but because I started to feel some mid-life lag in performance. I had no previous pumping experience and was just looking to strengthen my erections. I didn't want a sex toy, and I wasn't sure this device was just that, but after looking into review and different research I thought I'd give it a shot. Wow, just wow. Admittedly it isn't the most comfortable thing to use, but the results are EXACTLY what I was looking for , and then some. The intensity of my orgasm is far beyond what I could experience even as a young man, and the firmness of my erection is twice that. My flacid size is at least 50% of what it was, and my erect size is definitely thicker, and I would say slightly longer after 3 months of continuous use. Sorry I don't have exact numbers. I wasn't really into it for size gains. Suffice it to say that I was very average to start, and have built up slightly since then. What I can say is this device definitely made my sex life better, and my wife agrees even if it did lead to another pregnancy 😉. This daddy is VERY happy with his results.

Longer and thicker

I definitely love using the Hydro7! I use it for about 15 minutes and my dick gets noticeably longer and thicker and I usually have sex with my wife right after and she loves it! I definitely fill her up even more!
