I don't have any experience with these particular motors or controllers, but I had a Kelling (rebadged Chinese) DC speed controller, which was positively dangerous.
Had high and low voltage AC and DC close together inside a plastic box, just waiting for a finger in the wrong place and chucked out horrible interference.
The picture of the controller is 6 years old and he does not sell it on his other site.
People like this seem to be cheaper and their products certainly look more professional

Sure someone will have experience of similar motors / controllers.
