To be honest though if your in a position to get your bodyweight behind the driver i think these yankee drivers are absolutely fantastic.
Only downside i found was if your up a ladder and struggling to get some leverage behind the driver.
Still great to see then again though, brings back memories of me Dad doing DIY with his other latest toy the Workmate
I know what you mean about using them up ladders, had my fair share of slips with them too, especially using slotted screws. Lol
