This is a great product, and after using it a few times to get the hang of it, I would recommend this product to anyone.The only thing that lets it down is the lack of any understandable instructions, which is why I only gave it 4 stars.A tip for anyone buying this machine; Watch the videos on You Tube by David Gladden. 3 videos there that will get you up and running. Have a practice on some totally wrecked blades to get the hang of it. I even managed to rescue a 10" disc that I used for cutting up some old timber with nails, and all sorts of crap on it.Get it bought.Haroldine
