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.

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.
Hello nice thread ..I just purchased on a whim by shear accident a product called battery-last ..Its a gel sorbotane half sphere that isolates a boat battery.I placed them under a preamp and mulit disc player and they seem to work just like the expensive stuff for a whole lot less..
