Anyone tried military grade anti vibration feet ?


I came across this listing on ebay where the item is a vibration isolation feet used for military purpose to isolate electronics in military vehicles. Here is a link:

Has anyone tried something like this ? As with many other products like Vibraplane, industrial products which are scientifically designed do go well with many of our audio applications. Looking for some experience here.

At first glance I thought they were motor mounts from my Norton 750 Commando.
If your equipment has cone feet and isn't too heavy, you might try some anti-vibration pads for telescopes. I haven't tried them myself but a friend of mine swears by them. They are inexpensive but they only come in a pack of 3. You can get them from amazon.com.
I use common butyl rubber chemical bottle stoppers. Size 10.
I must have 50 of them..
Cheap $1.50 each (lately hard to find.. I got mine locally at a American Science and Surplus outlet. Their website does not have them)
Solid chunk of bytyl rubber.
An alternative:
Non-audiophile Sorbothane half domes cost way less than 'audiophile' ones.. at Amazon.
