It's not clear WHICH brand the OP is even talking about. He mentions "Hypervolt" in the first sentence, but that's not his company. Hyperice makes Hypervolt (https://hyperice.com/about-us/).
It sounds like this is a knock-off vendor complaining about another knock-off vendor. The OP, "David", links to a youtube video where the poster is "Jimmy Den" (https://www.youtube.com/watch?v=zb7U8vOE4N8).
Am I wrong here? Are fabless vendors, composed of a few people, who basically rebrand white-label shit from alibaba really making (and perhaps in this case losing) millions of dollars in time-frames of months to a couple of years ??
