I got this to save me money on my Dewalt planer blades. Set up is straight forward and easy. I have used it now for 2 yrs and it works great. Pull it out and set it up and you can have your planer blades sharp in 15 to 20 minutes. That's alot better than spending $50.00 a pop on blades. I have already paid for this with resharpening the 5 blades I had purchased before getting this. Great tool, it does kinda make a mess though.
