I bought a generic better than this one at my local hardware store. The hot and neutral wires are unmarked, and the overall insulation seems cheap. There are only wires, then a thick layer of insulation covers them, that's all. The Utilitech I picked up had ground, hot, and neutral wires, each with a different colored insulation, and then all three wires were wrapped in a thick layer of black insulation. Just go to your local hardware store.
