How much mileage out of a diamond fret file?

I've been using StewMac's straight diamond crowning file for probably two years now, and it's been great. It's still cutting well enough, though perhaps not as quickly lately. I know regular files will wear with time and use, though this is my first experience with a quality diamond file. Not sure if it's in my mind or not, so I figured I'd see what kind of mileage the rest of the tech crew is getting. Thoughts?

I had an old one, from Stew-Mac before they were Stew-Mac. It says "Guitar Shop Supplies, Ohio" on it, if memory serves. It was perfectly fine all these years and my favorite fret file. Until I let somebody talk me into a stainless steel fret job, which completely ruined the file in one session.

I'm still bitter about that, the current Stew-Mac diamond files are different and I don't like them as much.
