One of our lead mentors, Mr. Swanson, would swear his life to Craftsman products, do to the lifetime warranty, and I'm sure he'd tell you to take it back to the store
As with any electrical situation, you can always use a multimeter to ohm out what each terminal actually does. Weather or not you want to keep the receptacle hot all the time or not, Al and Don's descriptions are wonderful.
And be sure that your wires are not only tight under the screws, but that you didn't nick them while stripping, so that they might break off. After you securely fasten the wires under each screw, give the wire a few good wiggles to ensure that it doesn't come undone, or break off.
