excellent product! I have been using my original model for 5 yrs now and have always had the complant that it is a little flimsy when filing and the professional model is awesome. no flex at all. much better than lightweight model. take it from a landscaper. well worth it if you are wanting to sharpen your own chains. instructions are fairly easy to follow even for a beginner. oregon has an excellent website also that helps. If you take your time and learn how to use this tool properly you will be pleased with the cut! Get more detail about Oregon 23736A Professional Chain Saw Bar-Mount Filing Guide.
