Three years ago, I tried sharpening drill bits with a cheap sharpener. I got frustrated because it was hard to use and I didn't get very good results most of the time. The old sharpener would make the bits worse instead of better.
This summer, I finally bought the expensive Drill Doctor 750X. It is much easier to use, and actually works! It's faster and more precise. So far I've been getting great results with it.
