It's a "must have tool" if you have drill bits. Easy to use and the results are spectacular, especially if you are drilling steel.

there are several models of the drill doctor - they work OK, but the older ones have a problem holding a consistent relief angle - sometimes you get negative relief and the drill doesn't do anything. But, it's a lot cheaper than the $6000 Darex
I worked as a machinist for about 8 years running a drilling department. We used everything from .015 up to 3". I watched the tool crib guy hand sharpen drills and thought it looked easy. Tried it myself a few times and found it was easy. If you have an eye for it, it becomes very easy after a few tries and only requires a bench grinder with a squared up wheel. If you have a bench grinder and wheel dresser try it out a bit before you buy a drill doctor. You may find you don't need it.
I have a slightly larger model which has a gizmo for setting the drill correctly in the holder.. Looks like this one you do that on your own. Just works on standard twist drill bits and I think concrete bits.. Haven't sharpened any of the latter, but it's a fast, handy, no-brainer sharpener for twist drills.. Won't work on brad point drills, etc..
Yes, got one for Christmas 2 or 3 years ago. I had a cigar box full of dull bits and sharpened the whole lot. It worked well. Will not sharpen brad points, spade bits or Forstners, of course. I wish I had a forstner bit sharpener.

I've got all that stuff and have piddled at sharpening some, but I was thinking of semi-automatic mechanized sharpening.
I agree with some of the posts.
I have a different model - 3/4" max size - and it turns a rounded tip - not two flats. I can cut cross points - that is great.
I saved a chipped 3/4" drill - high quality - and after grinding it I then hand ground the flutes for a undercut from the cutting edge.
I do a lot by hand, but preform some extensive jobs with mine.
