So far so good
Only used once so far but it did a great job and has plenty of power.  Seems to be a better shape with the 6th blade to conform to the shape of your scalp.  Only draw back is one of the center pieces either came off immediately or was not included when it arrived.  Purely esthetic and doesn't effect the performance of the blade. Just glue on the keep the surfaces even.
