I look at most of the old tech advertised for “clean power”
The chassi internals on the Tice device is filled with circuit boards with little more than one or two passive of incredibly modest values or a bunch of connectors that make it look deceptively busy (complex - like it all does something) and yet be woefully wanting in what needs to be done to incoming AC to truly address the major issues resident in transmitted AC.
I couldn’t sleep at night if I put something out like that or the old Hydra.
Sheesh!!!
