Well the copy does get across a proposition. It is, quite literally and figuratively "in your face" about that proposition. You make some bold claims I think would sound better in testimonial form.

The layout is pretty clean and layout seems to make sense. The only way to make certain is have a customer go from browse to purchase. Then you can be sure real use produces real information.

The site is okay. I would suggest a more formal profile of your target customer. This may or may not suggest a different layout. Personally I didn't get a feel for a customer likely to buy this product. With a better understanding of who buys it and why (expressed in copy) other people who may be cosidering this can make the decision to buy.
