I got one of these as a gift and it seems like a good idea, but the plastic tensioner broke under normal use.

I used this edger for about 3 tunes before it started to fail. The mechanism that tightens to hold the file in place must have stripped out, and it didn't allow the file to be held for more than a few passes on the ski. Not a very durable file guide. Also, it's pretty expensive for what it is. Look for a guide that files at a specific angle instead of an adjustable one, which I think are just prone to failure.

Just like a previous reviewer, the mechanism that tightens the file in place won't tighten anymore. It's too small for regular tuning anyway -- you can't really get a good grip on it, but easy to carry on a trip somewhere -- if it worked.

I haven't had it long enough to speak about durability, but other than that it seems to work quite well.

Works great when it works, but I broke two of these under normal use. As others have said, the tension adjuster failed. I have gone back to a simpler tool.

I used this thing twice and the tensioner broke on me..I couldn't tighten or loosen the file...I cant believe they charge this much for this POS!!
