Shiyang Marathon Type N7S S04 Micro Motor with Straight Nose Handpiece&Contra Angle

I would have given it a 5 if it had come with a manual for maintenance and operation.

Quality Hand Piece with Speed Control..... What Else Do You Need? :)

Did not have a 110 volt electrical plug but rather a hard to deal with adapter like one uses when traveling abroad. In addition, the variable speed component did not work right from the start.
