I bought the edge pro apex, kit number 4 as well as the small knife attachment. Had it unpacked and 2 knives sharpened in about 30 mins. My knives are not worth this setup but I wanted to start small and eventually get a good set of knives. It is rewarding to have a knife that my meaty arms could barely cut an onion before, to have the knife almost fall thru after sharpening. I would recommend the online Visc or the DVD, but if not, at least read the manual. I caught myself doing some of the things he suggests against, like swinging the arm way too wide. Well built product that works. And it was shipped and delivered in 2 days. Satisfied customer in oshawa.
