I DID NOT use it without a backing plate. I noticed the vibratiion when I turned it before the Meguiars plate was installed.

VIBRATION practically gone with backing plate.😀

I have had a 69924 for a couple of years that I plan to use for the first time in the near future. 

Hs anyone ever heard  of a DA polisher  that vibrates badly without  the backing plate attached..................  but, the vibration pretty much disappears with the backing plate attached?

I have replaced the OEM grease  as shown in several You Tube Videos and the OEM backing plate hasbeenreplaed with one from Meguars.
