To answer PEkid, I don't really think I have "gained" anything from the Bathmate. I have only had it for 2 months though.
However, I really do not think I will achieve permanent gains from it either, BUT the Bathmate is becoming a VITAL PART of my manual exercise routine! What it allows you to do is WARM UP TO THE HIGHEST DEGREE!!!
Now, the only reason I don't think that permanent gains can occur with the bathmate is that you cannot logically wear it easily like a regular pump for enough time. I mean, who sits in the bathtub or stays in the shower for an hour-an hour and a half? Plus, you know what happens to your fingers when they are in the water for very long? You see my point?
I REALLY enjoy using the Bathmate with water as hot as I can stand it to warm up, it makes for the BEST warmup ever.
BUT, if you are interested in REAL PUMPING, and the kind of pumping that I consider to be the kind that WILL produce PERMANENT GAINS, the Vacutech is the way to go. I can't tell you how above and beyond they are from all other regular pumps. I have tried ALL KINDS OF PUMPS, and sure you can find cheaper ones, but MAN let me tell you, YOU TOTALLY GET WHAT YOU PAY FOR!!!
Vacutech provides 3 of the most important necessities for optimal pumping.
1) a custom fit cylinder
2) a pump with a pressure gauge
3) the best customer service (of ANY product, not just penis products) I have ever experienced.
