When I last used Vibration Suppression Pads, the “suppressing” material was a
Sorbothane like substance, which has a property of dispersing shock waves effectively through the sides of the product rather than back towards the source.
When I ran a test on my GEM, I noticed that although the amplitude of the motion caused by a shock impact was similar to just using the GEM with no VSPs, the big difference was that using the VSPs allowed the GEM to stop vibrating in a much shorter period of time.

These were the Celestron VSP’s of purchased some 15 years ago.
