I'll second that, I have an Meade 8" SCT on an LXB500B mount, the previous owner had done everything to try and strengthen this mount/tripod to stop the vibration - he had added shot weight into the legs, added teflon runners to hold position on the adjustable legs etc

I removed all the mods, placed the tripod on the vibration pads and voila! - down to 1-2 second correction. They appear to be made of 3 parts, the base that sits on the concrete, a cup that the tripod leg sits in and a kind of gel in between - the gel is the vibration absorbing layer.
