| I would be interested in having a smaller pump. I don't mind being teathered by tubing, but I wish the pump was smaller. Currently when I wear a suit I either have to cut the pockets and run it through there, or have a funny bulge on one side of my jacket.
I could envision a small pump, not much larger than the catridge itself, which could be controlled by a wrist watch or similar device. A watch would be great because I'm pretty much always wearing one, but then again, if you went that route it would be something that most people would be willing to wear in a variety of social situations. |
