You'll like them, that's what I have been using for years. I got mine from my uncle back in the 90s when he was developing them in Rockford, they used to be black and gray instead of red. Then there was some royalty deal with Hansen and he has been selling them since under my uncles patent, unless he sold him the patent I am not sure of the details. I actually bought some more a few years ago from the store for my impact sockets I like them so much.
I just saw last night Lowes has a brand of them now, but the markings are down at the bottom, which would make them harder to see when you have them placed one in front of the other in the top of the toolbox. Made me wonder if the patent ran out or if they copied around the patent or something. Either way, I like the Hansen ones better, easier to read and made in WI, USA.
