It is likely that the problem is the 'CE' mark certification that all
products need to be sold in Europe. It is 90% protectionist Eurobullshit,
that every manufacturer has to go through, and it is expensive. A small
company like riffmaster may not be able to afford it.
Those Europeans reading this may wish to thank their governments for
keeping innovative products from smaller US companies out of their hands.
There is an option called self-certification that RM may wish to explore.
