Townshend Seismic Isolation Podium

I understand the physics behind isolation and the sonic benefits that decoupling achieves, and I am seriously considering purchasing a set for my KEF R11’s. (I currently use an ISO Acoustic Aperta 300 for my R2c, as well as some older ISO-A stands for a set of LSX). I am wondering if anyone here has any experience with Townshend Podiums in particular, and can give a thumbs up or down. Thx !
