At this price point it seems to be great quality. I have used it on 3 guitars now and it works great. A fret file is such an easy way to shape the frets after leveling them. This file is perfect if you're looking to start learning fret leveling and dressing without breaking the bank.
A couple of things to know:
Just like many other fret files, even much more expensive, there can be a build up of fret metal in the file. I just use a cheap brass brush to brush it off.
The widht and radius of this file seems to be about 2,5 mm. That means it's a good allroung file for many types of frets. I have used it on both more narrow and wider frets. With medium jumbo frets (2,7 mm wide) I wiggled the file from side to side a little to reach the whole width. Otherwise it might leave a microscopic "shelf" on the sides of the frets that won't be even.
Onece again, a great file over all!
