i,to think the video is not really a fair comparison,but i can relate to it.
before i got my c12,i worked with a 12v.hilti and a 18v. milwaukee.
(you can't beat a hilti!)i smoked the milwaukee,that supposed to be more powerful and last longer.
i still have my hilti( needs new batteries,8 years old).the milwaukee,in the trash!
i never liked the drill anyway so i didn't bother with to get it repaired.it was 11/2 year old.
i used the milwaukee mainly for drilling,3/16 solid bit,hole saw from 1" to 3"but usually on 1/4" panel and sometime 1/2 ply or part.board.
festool claims that you can't hurt the motor on the c12. working with the c12 for almost 3 years now,i believe it!
