I am in hopes that you will use this machine awhile and then post a fine review. Not only am I very curious about these machines maybe it will shed some light into the murky replies I get from my dealer and perhaps others on this site. My dealer has one and will sharpen only those blades that are pretty straight and simple. For example he will sharpen most blades on lawntractors and ZTRs but not most push mower blades. He claims that his machine will not do those blades like mulching blades for example. I have always wondered if he is just to lazy to reset his machine, does not want to bother, has a problem with liability, or if a person needs a different machine for different blades.
