I'd found your product a good bit before you guys became a sponsor here, but like lonestar, I haven't been able to afford one, was lazy, or whatnot. Then I was laid off in December making things harder.
Do I find your product interesting? Most definitely. When I was commuting 100+ miles a day, I'm sure the Bowsprit would've been handy. For home, I don't have too many places where I could place the Executive and leave it, however, I'm hoping that will change soon.
In some respects, one could look at your product and say that it just looks like a different pipe holder and not know exactly how true it is. By this, I mean that looking at it, I wouldn't be able to tell someone how it functions. How does it hold the pipe in place in the car? How well does it hold the pipe in the car while turning, going over bumps, etc. For this I would suggest maybe a demonstration video placed on your site.
Another tip would be to have links to Facebook, Twitter, and other social networking sites.
