Interesting set! Let's you experience all the different handle styles.
But:
I've never seen black/yellow handled insulated screwdrivers from Wera before and I think it's beyond stupid and begging for an accident. Black/yellow is the combination for the 900 series which are not insulated and have a metal butt/strike cap - something you definitely not want to use around electricity. And now they're mixing this up by releasing insulated screwdrivers in the same color combination? Not the best idea, imho - ymmv.
Kind regards,
