As a result of using this accessory, I found that switching sockets is a breeze and saves me time during repairs. The size markings are easy to read and the unit is built to last. The only drawback is that it only works with Craftsman tools.
Bought these for my neighbor as a Christmas present along with a metric set. It didn't have hex heads and kept complaining that the bolts had snapped off. He likes her.
I ordered a set of 11 sockets, instead I received a socket wrench, 3" extension and 9 sockets in a huge plastic carrying case which I received don't need. Someone threw a ball here. I think I should take what I can get. But now I need to buy a socket holder to hold my sockets in my tool bag.
