I've just started using the beta and it's very promising and very professional: not a hack at all. The manual is beta also, obviously, but it's already one of the better manuals I've run across: brief, clear and concise. Took me about 10 minutes to scan the manual and start playing with it, maybe 30 minutes before I felt comfortable using it for real.
The software gives you the choice of fully automated, just push the button and watch it work; or you can watch it calibrate your camera and it will tell you what MA to dial in. I've done microadjustment enough to be comfortable doing it by hand but this is far easier and quicker - from 3 to 5 minutes per camera / lens combination.
I've only done a few cameras and lenses so I won't comment on accuracy yet, but the product is NOT a hack or some firmware add on. It's a very nicely done piece of software.
