This is my thought as well. We had a problem with the hard drive on our DVR. We exchanged it for another one...same problem. A third? Happened again! The company finally figured out that it was a bad lot and got rid of them all and then we finally got a working one.

Happens in manufacturing all the time.

I have Panaracer Stradius Pros' on my bike and after more than 3000 miles, they are still in great condition.
