Has anyone tried these for turntable isolation?

They are made by Triton Audio, who are makers of professional recording gear, like mic preamps and such.

They specifically market these as use for studios to use under monitors, but they also list turntables as a possible use.

They are only about $45, which by home audio standards, is ridiculously cheap. But they seem like they may actually be good.

I have a Chinese made magnetically levitated platform that I got from Grant Audio years back somewhere.  I haven't used it for a while as I really did not notice any improvement over Stillpoints.  I may go back and try just the footers with out the platform like these guys.
