Plastic. And beyond that it will rattle when starting it up. I don’t notice it once it is up to sapped but I have only used the lowest speed as anything above feels too fast, or in other words I don’t need or feel comfortable using them.
Sorry, there was a problem. Please try again later.Plastic. This causes vibrations when starting it up that are annoying. Once mine is running at speed there is not rattling. If there were the solution would involve tightening the mounting screw of possibly placing something like a thin layer of plastic tape around the location where the mounting screws touch the plastic housing.
