New Web Site -- Can you critique?

The site is www.RainReadyPen.com, A Materials scientist but he has combined his materials skills with simple entrepreneurship, developing a new product I think nearly everyone with want. It is called the Pen-brella, and as its name implies, it fits in your top pocket and is, in fact, a working ball-point pen, but when rain threatens you always have your umbrella with you.It’s not meant for an all-day umbrella, It’s for that dash from the mall to the car where you left your big umbrella. But who hasn’t been there.

I’d sure appreciate if fellow Fluther users would look it over and tell me of things that need to be simplified or made more obvious.
