Ive got their smaller machine but its the accurate one, their customer service is very good and the machine is built well the only thing I am having problems with is it seems the Z axis is running out but I think its to do with the base. I use my machine to mill PCBs. I would say its good for wood etc but I tired to mill aluminium and its completly useless for it. The Z axis plate that the router mounts to is plastic so it flexs to much to mill any metals.
