Don't forget, the true cost of a product is not really reflected by the sum of it's parts !!
Don't forget, R&D, Engineering, Prototypes, Testing, Beta-Testing, Software Programming, Tooling, assembly, Marketing, Distribution, Sales Commisions, Tech Support, Warranty claims, etc, etc,etc, ....
PLUS, you still have to sell a VERY LARGE number of a product like this to even begin to DREAM about making a profit.
