Well conceived socket organizers (I bought 2 each of the 1/4, 3/8 and 1/2 drive - for metric and english) that do what you expect. My only quibble, and it's a small one, is that the width of the spaces required that I skip one slot somewhere between my 1/4" and my 1/2" sockets, because the 1/4 fit fine in the first slot, but the 1/2 was too thick to fit with a standard progression of sizes.
