While this trimmer might be fine for quick roundovers and the like, it lacks the refinement and precision necessary for fine woodworking and production work. Careful observers will notice that the base and motor are not perfectly perpendicular to one another. There is too much slop in the height adjustment mechanism and set knob. Too, the base itself is not perfectly flat (place a sheet of 400 grit sandpaper on a flat table and run the base plate over it a few times. High and low spots will quickly become apparent.) All in all, the 7310 is very underwhelming in its quality and precision. As far as the "Rotozip" style trimmers go, the DeWalt and Bosch models offer better quality and refinement then this PC, though they, too, suffer from some of the same problems.
