To give customers an easier way to find the Bathmate penis pump that’s perfect for them, we’ve recently renamed all of our pumps – the Hydromax9 used to be known as the Bathmate Hydromax X40, and still delivers the same fantastic performance.

When you buy directly through this website, you can be sure of getting a real Bathmate, along with some fantastic additions. We provide free worldwide shipping (though expedited options are also available), a full 60-day no-questions-asked return policy, and a complete 2-year warranty for your Bathmate Hydromax9.

To get the best results using the Hydromax9, just fill with warm water and seal against your body for a 5 minute session, release the pressure and repeat twice for a total of 15 minutes of use. Carried out regularly, this will result in a real improvement for erection hardness and personal confidence.

With our full range of Bathmate hydropumps, we’ve helped over 1 million users across the world. Over in our Bathmate Reviews section, you can see how much of an impact we’ve had for users, while our Bathmate Videos page gives you a chance to see the changes for yourself.

While our Hydromax9 pump and smaller options should suit just about any users, if 9 inches isn’t enough, take a look at the biggest penis pump in the world – the Bathmate HydroXtreme11!

So far this Hydromax9 is simply amazing!

The resulting final pump leaves me even more confident! Love the pump feel and weight that last all day long.

Got compliments on my results in less than a week immediately after sex. Difference in girth and length was noted.

Undecided.... needs more time ...

Works pretty well, occasional issues with nut entrapment. Got to find the sweet spot or figure out ways to keep it on the outside. Otherwise I love the feel. 🤪🤪

Anyway I bought bathmate 9 hydromax. If anyone is wondering you should only buy 9 if you are 6.75 or larger. I have been doing some manual exercises prior to buying bathmate but I wanted smt better and more efficient. Been using it for about 2 weeks now and so far its been good. You should not expect any substantial results right away tho. It will take at least a few months to notice a noticable difference. But you also get short term effect and for like 6 or 8 hours after bathmate session you D will definetely be a bit bigger. Esp flacid size. So if you want to have fun with a girl you can use it before date or whatever. The shipping was free and took about two weeks. Not much to complain about. I will give bathmate 9 four stars just because of the price. But overall its a great device for girth/thickness and a bit of lenght.
