Ive been pumping with a vacu-tech pump for a little over a year now. There are times when I seem to get good gains but still had trouble packing the tubes most oftem. I decided for shits and giggles to try a bathmate and used it for the first time this morning and have to say my initial impression was very good. In that first session I got more girth than I ever have with a standard pump. Cant wait to see what happens after a few months of daily use.
