After seeing this video (had no idea this tool existed) I gave it a shot for $65.  I have three disc brake bikes in the house - my GR201 gravel bike, R088 roadie, and my wife's Liv aluminum gravel bike.   I have spent a ton of time on all three trying to get these to not rub, with mixed success and a lot of cursing.  Got this tool in, set this up and went to it.  All three bikes had the front well out - the back on all three was ok.  The improvement was massive; the front brakes are now dead straight.  Totally worth the money.   

As with these kind of instruments that make irreparable changes the key is to take the minimum off - I marked the surface to be machined (as in the video) and took the minimum off.  The minimum being 75% flat surface or so.  Went slow, checked often with no pressure other than the light spring (which was more than enough to remove material).  It did not take long to remove what needed to go.

Big thumbs up on this tool.

Tried this on my VeloBuild aero gravel and it works well, there is some very minor play between the interface on the final part between the grinding disc and the arm. Apart from that so far so good.
Faced mounts so far with a simple file and trying the caliper on which quite a bit of time because you are constantly taking off the caliper.

My procedure with file facing is: have the wheel on with the disc, mount caliper WITHOUT the brake pads and tighten either bolt and see what happens between caliper and the disc and then file to opposite direction.

With this it just seems simpler.

Facing with a file I get to "good enough" and with this while not perfection I get most the way there.

Bonus points that my VeloBuild front thru axle does not fit to the front axle fitting lol, tried TanTan thru axle and it works.

That’s almost as expensive as the ParkTool one.
