Again, we are not comparing the first generation Griots with the made in the US PC. We are comparing the third or so generation Griots with the current made in China/Mexico Porter Cable. A simple search in this forum will reveal that in the last two months there have been something like 8 or 9 PC issues---more so in the same period of time than any other DA buffer. This is the reality in the present; if you prefer to live in the past, fine. Of course, no question the Meguiars has had the most issues with the current generations.
