Im not a Dewalt person myself (first Dewalt for me), but can't argue they are quality tools, could probably stand next to Makita, Milwaukee, etc... And yes, i know one must be careful with the last turn thats why i went with this particular tool - on straightened position it acts like a regular screwdriver - thus you can make the last turn with it.
Though can you enlighten me about these "Punch settings"? No clue what are you talking about 🙂
Regarding gears - still using stock gears since i newer had any issues with them.
