Funk Firm Bearing ?

[richluvsound]

Hi Folks ,

I hope everyone is well in this crazy time ....

I'm wondering if any has bought and used the bearing uggrade from Funk Firm ? I've orderer and paid for one ,but having seen the quality of the "Boing Feet"
alarm bells are going off . I can't find any drawings of how they are made and the materials used .

I read a few reviews but even they seem a liitle vague ..

Any happy customers out there ?

Hope I've posted this in the appropriate section ?

many thanks , Richard

I have a Funk Firm bearing. No complaints from me.

i must admit some of the funk firms offerings are laughably expensive for what they are
