I purchased earlier this year 2 wind turbines from Exmork in China, so far in high winds both units have failed badly one off killing the controller and the other burning out the turbine itself.
I have found that the manufactures have failed to offer warranty and have now sent over 30 emails with pictures and still they are not helpful.
the moral of this story is don't buy Exmork wind turbines, they don't protect themselves in high winds and fail!!
