I have a Venus much older than that, from 1999 or 2000. I also stopped using it very often because of the required set up time and clean up time. But now that I am getting older and erections require more concentration, I’ve decided to try it again. I also have just order new liner, end cap and small cap and saw the air control box when I was ordering. Will it work with my old Venus? Does it require a battery? I still have the clamp and remember sucking the small hose and clamping it to adjust the depth and length of the stroke. Does the new air box do that?
