I have six sons and two sons-in-law, and in memory of what their father always did, I try to buy some little, indispensable tool at Christmas for them. Clearly this little socket was a real winner. One son mentioned that he had seen it advertised and wanted it, but had to wanted to spend the money! They all loved it. I got one for myself as I am always searching through my husband's tools for the correct size socket. Great idea.
