Awesome product.
Unfortunately, your price point is, to be blunt, retarded.
yes, and also minimum 300pcs/order is little bit stupid.) I expect, that it is final product, not like ASIC chips, so don't see any reason, why it will be send in hundreds per order.
10pcs minumum and price about 1BTC and you will have huge demand. your terms only leads to group buy and resending units between forum members.
otherwise, don't think, that you will be successful with you current policy.
