I think the grinder is great. I bought it to sharpen my own blades to save the cost of having others sharpen them and the time it takes to drop them off and pick them up. It is a little expensive for residential use, but I was sharpening 6 blades, twice per year, which cost about $80/yr. This grinder will pay for itself in about 7 years, which is good enough for me. I would prefer some sort of quick-clamping feature to lock in the wheel height, instead of the triangular nuts, but, all in all it is well made, durable and easy to use.
