Product Description

The Bathmate Hydromax X40 is the ultimate in hydro-technology for penis development and health. It’s 15% bigger than Hydromax X30 and offers all that Hercules can do and even more!

  • The Bellows system now incorporates a new soft sealing – full support comfort ring which provides you with reduced pressure and greater comfort around the penis base and testicle region. As an added bonus, it is also removable for ease of cleaning.
  • A new Swivel Bellows feature allows for full 360 degree positive rotation that gives you entire visual chamber viewing plus inclined angle change option for optimum efficiency when used in the bath or shower – or when you are using the amazing new Hydromax pleasure ring system.
  • A new Super Flow Latch Valve system gives the opportunity for one hand filling in the shower which makes using and positioning the hydro pump much convenient for you.
  • A new metric and imperial guidance scale gives you improved visual viewing area, plus upper and lower texturing on the vacuum tube for better grip and control.
  • The internal bellows size has been increased and the number of convolutions reduced to allow you reaching even more impressive girth expansion.

    I used the Bathmate Hercules everyday for about a month. I loved it and saw great results. Unfortunately my penis was touching the sides at full expansion so I wanted a bigger one. I contacted Lovehoney, where I purchased my Hercules, and they recommended the x40. I’ve been using the X40 for two weeks and it’s amazing. It’s unbelievably easy to increase your penis size using this pump. What I like the most is it’s completely safe. If you’re worried about over pumping and hurting yourself it’s almost impossible. I’d recommend this pump to anyone. The results are amazing.

    We were surprised at the size of it and at the quality of it. It comes with the pump and a spare release valve. Hubby jumped straight in the bath a got to work! He said there was a worrying feeling of one of his testicles being sucked up inside and the base of it was digging into him. So the night after he tried it in the shower and said it was much easier to use, no digging in. No feeling of testicles being sucked up. I was extremely happy with the results and continue to be. If you are going to buy any penis pump, it would have to be this!

    I got this after I outgrew the Bathmate Hercules. It is essentially like the Herc yet bigger. It is definitely more comfortable than its predecessor and I am certainly not going to outgrow this bad boy. I am not sure if the pressure is as much as 30% more than the Herc and the increased size of chamber makes it more unwieldy and air bubbles are harder to avoid. I also like the dual measurement scale in both inches and cm. Overall it brilliant. I added 3cm with the Hercules and look forward to seeing what the x40 can do long-term

    Comparing with Hercules it’s a revolutionary breakthrough without a doubt! I like the design and the way it feels, but still not guarantee three promised inches!

    The feeling is pleasant, but a bit too “hard core” for me. May be I choose a wrong model to my size?

    It’s very comfortable feeling when you have this on. But the increase is not as significant as I expected.

    I first purchased the Hercules a few months ago, and within a couple of months my penis expanded to the point where it filled up the device all the way around so I had no more room to grow, plus it was pinching and leaving marks on the base of the penis which caused me some pain and prevented me from using it after awhile . My girth was already close to 6 inches around at the time, so I didn’t have much room to grow to begin with, but I didn’t realize this until later on. I was amazed however though after using it how huge my penis got. My sessions last anywhere from 30-45 minutes and believe me, if you hold out for that long your penis will look like a monster and feel amazing! And your gains will come faster. Swelling and bruising will occur, but in my experience, this has been the best method for growth as the short intervals and only doing a session for 15 minutes isn’t long enough for your penis to take the time to really expand and to really push it to the max. After your penis fills up the pump completely, you wont be able to pump anymore for safety reasons. So sometimes pumping as hard as you can to the max will allow your penis to expand quickly, but after a few minutes, you’ll be able to pump again as your penis grows, the trick is to pump as fast and hard as you can before the swelling takes place, because once your penis swells up fully inside the chamber, you wont be able to pump anymore. Well after buying the X40 I was shocked on how huge it is! I thought to myself “this thing is a penis pumper tank” compared to the Hercules. Well after my first session, I couldn’t believe how massive my cock looked afterwards. I measured the girth after my session, and it was at 7.5 inches around! It blew up and looked incredible, and mutated like in good way! But the best thing was, no pain or pinching around the base of the shaft and testicles, and no markings as the increased size has allowed my penis to grow even more plus it feels amazing and you definitely get much more hornier afterwards. My length gains hasn’t been so great, I base this off the fact that I outgrew the Hercules fairly quickly, but the X40 produces even higher suction power and with it’s larger size, I am hoping for better length gains as my penis will be able to expand much greater now not just in girth, but in length as well. Overall I am very happy with my purchase, the unit is well constructed and built to last. Some people might have gains within a month or 2, some people it might take 6 months. Just don’t give up and if your penis is rubbing against the walls of the device, well that means it is working and it is time to upgrade to one of the larger pumps. I will report back again once I start seeing higher gains. But as of now I’ve gained a half an inch in length, and slightly less than a half inch in girth. So I am currently 6.6 inches long and about 6.2 inches in girth.
