These are not original belts but they work great. In fact I think they last longer than the original belts, probably because they aren't as thick and therefore don't have as much internal friction as they flex around the motor shaft. I ordered them a while ago and I'm still using the first strap. An added benefit of their thinness is that I can fit the other two into the spare belt slot on the drive head.
