I picked up one of the cheap ones about 35 years ago. Still have it but don't use it. could never remember which way to twist the collar for in & out. Now I use a De Walt 1/4" battery impact driver. Haven't hit my hand once since I started using it.
Those battery powered one makes teardowns a whole lot faster
