Saris H3 noise is like to a hammer knocking inside.

We believed the message from the Saris ad but apparently something went wrong with the design of the Smart Trainer H3.

Why are so many users submitting complaints online with posts and videos about the “TOC TOC TOC” the annoying noise that H3 emits?
We’ve listed some videos and posts documenting the problem, hoping Saris will come forward.
We ask Saris to write to us so that we can make their strategy to remedy the problem public to all.
L’ho comprato in Italia. Anche a me H3 ha dato lo stesso problema! E’ successo dopo circa 30/40 minuti. Quando si passa da una potenza alta a una bassa. Poi dopo circa un’ora che rimane spento torna tutto apposto
Tengo el mismo problema, a los 2 meses de comprado el trainer empezaron los ruidos, escribi a saris y me indicaron que ajustara unos de los tornillos internos, que al parecer alguno estaba suelto, al final como que se solucionó ajustando el perno del tensor de la banda; pero el problema volvio despues de unos meses, suele sonar cuando ya está caliente el trainer y se le mete mas de 250w de potencia.
Si alguien sabe donde esta el problema exacto para que publique el dato… les quedaremos muy agradecidos.
I put mass in the ball bearings of the R8VV tensioner and the noise disappeared.
Could you send an image or video to understand how to do it? What is R8VV?
