I've looked at one of those sockets - and for the life of me, can't see them surviving hard work. They are clunky big for tight spaces though might be fine for a ham handed suburbia homeowner that has a minimum of tools(like my next door neighbor). For those nuts that don't want to come loose, Vise Grips (I have them, the real ones, from 4" to 10"), or a BFH and a chisel. Then if those fail, fire up the torch
