The problem with blatant copying like this is , while China does have copyright laws they aren't worth the paper they are written on. They fiercely protect their own and only way you will get any justice is to pay a bunch of corrupted government officials to actually exercise the laws that are in place. Other than that I doubt much can be done.

This is bad. Really bad IMO and if these copied ESCs perform well that could be even worse. If they drive Castle out of business who will innovate and develop new ESCs. The copycats sure wont and probably wouldn't know how to anyway. What makes me wonder is why no one is copying the Euro ESCs like MGM and Schulze???? Surely them being more expensive there would be even greater profit margin. Why are they almost always picking on Castle? Anyone have theory on this?

I hope you get some sort of positive outcome out of this Patrick.
