It was seriously misfiring screws, just flipping them out on to the floor. Plus the screw depths weren't consistent. In a row on a board, some were in too far, some were OK and some were sticking out. For metal stud construction where you would normally offer the screw up then squeeze the trigger before you push, you can't do that with the Festool because pressing it activates the motor, so the screw will slip off the metal when you apply pressure and before the motor engages. I deemed it not suitable for everyday use. Fine for a tool whore builder that boards a three or four houses a year, but no good for a dryliner. The Festool rep came out and saw how it was playing up and all he initially offered me was a few boxes of screws. I managed to get a new collated end off him but wasn't prepared to give it another chance because it did the same with a new end that he tried. It's a piece of s**t.
