Nice. Very nice. The simplicity is extremely appealing. I'm going to jump on the "price too high" bandwagon as well. Unless you really need that price to cover costs and make any profit at all, I'm going to suggest that you can make more money selling them for just a little less.

You're sitting right at that point where a slight ease in price is going to result in a significant increase in quantity sold. Unless your production capacity is constrained or you're already very near your break-even point on cost/price, charge less and sell more.
