Yeah they are "industrial quality" and they are "indestructable" but to make them like that precise play, light touch etc are compromised in my opinion. They are designed to work only when really bashed, unles they are brand new and then I guess they would work ok but the very tough rubber grommet used to restrict movement really does restrict your movement. They are generally considered the cheap nasty way to go as far as BYOAC but they have their place.
