My current strippers aren't automatic and still require me
to do a certain amount of the work.

I've used all sorts of stripper, manual and automatic. However, one type I
always come back to is the type illustrated below.

They are simply fantastic. Simply insert wire and squeeze handles. No fuss
whatsoever. Very clean cut, no adjustment required. They simply work. The
idea of using pliers makes me cringe!
