QSA Power Jitter Power Conditioner, anyone tried it?

I’ve got a Yellow one on order. Has anyone else tried it? I have the QSA stones in several places in my system. I tried the light blue fuses, and liked them, but ended up replacing them with the SR purples. This Power Jitter seems like a good way for someone who is is open to these kind of tweaks, but doesn’t want to mess around with fuses, to try QSA.
