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
