I have, based on Ashley Hobson's preliminary evaluation, bit the bullet and acquired it:-It is indeed revolutionary. Not in any of its details but in the way they've put together all those details to form an entity which permits ANY BEGINNER to immediately achieve near perfectly sharpened tools.-In all of my seven years of woodturning, I have never had so well sharpened tools as today - just after "inaugurating" my machine, that is.-It has instantly improved my cuts to the extent that my sanding is reduced by about 33%-It seemingly reduces WEAR of your tools too.-Conclusion: Though it looks expensive at first glance, it's a VERY good purchase, worth every penny of it! (they ought to pay me a commission...)
