First I will start by saying that this is the first and only dedicated blade sharpener that I have owned. I did research on a couple others and decided to purchase this one. I have three Toro zero turns, one garden tractor with mulching blades and another zero turn with a steering wheel. I sharpen a few blades during the course of a season and sharpening with the angle grinder was getting old. When I ordered this one I decided to save a few bucks I would buy a blemished unit and I'm glad I did. I also purchased the stand and the wheel kit for the stand at the same time (I already had the blade balancer). I received all of it very quickly after I ordered and it and it shipped complete. They said this was a blemished unit but I couldn't tell, it looked brand new! I put everything together, which was easy and straight forward and was sharpening blades in no time. It's very smooth and easy to use and puts the correct angle on the edge of the blade flawlessly when you follow the correct settings. Unit has plenty of power and I've never had an issue with it bogging down or stopping. Makes a job that I used to dread something more enjoyable, not to mention way faster!
