The average performance is on a high level, you can very quickly cut by 22er plates. The heating of the material remains within limits, which indicates a long service life. The average image performance, however, was better with my old original BOSCH sheet. When laminated boards are produced at the edges but little runaway - whatever the "train speed" of the saw. Of course, one has in this price no maximum number cutting teeth, but I was hoping for absolutely smooth cut edges due to the excellent reviews. As a percentage of purchase price still obtained but a good blade that makes a neat interface - just not perfectly smooth. That's why good 4 stars.
