I run a small engine repair shop and I work on a lot of chainsaws. I needed to be able to sharpen the chains. Well, the lowest cost quality sharpener I can find is a $200.00 Oregon. I can't afford that right now but I had to have something NOW. So I had no choice but to take a chance on the absolute cheapest sharpener I could find. So I bought the Buffalo Tools sharpener. You can't imagine how shocked I was when I realized it actually works! I've sharpened several chains with it and it works GREAT! First off, DON'T BE AN IDIOT. It's PLASTIC, the threaded parts are PLASTIC, DO NOT OVER TIGHTEN ANYTHING THAT IS PLASTIC!!! Have I stressed that enough? Most of the bad reviews I've seen are from people that over tighten everything and break or strip out the plastic. Take it easy with this thing and you'll be fine. One thing I noticed is the clear plastic guard you have to look through is thick and distorts what you're looking at. Take it off and throw it away. You also have to turn the motor off between each cut. This is no big deal because where you drape your hand over the top of the unit to pull it down your fingers rest right on the on/off buttons and they click on and off very easily. After one chain you'll be doing this automatically. For under $40.00 I couldn't be happier. Some day I'll get me a good Oregon sharpener but until then this will do just fine.
