I have the Orange/black Klein insulated drivers in this style, I’ve not needed to get them out of my tool bag for 2 weeks, this is awesome, I also have the 4 in 1 stubby, and the 4 in 1 precision slim driver. These 3 drivers which cost about £50 are retiring the 5 insulated ones which cost £230 ( I do very little electrical work these days though ). Just buy them, you won’t be disappointed.
