Surely the picture should be from this page?
Those rubber thingies have been on the market for years. They might have added number 2 in the end, but I don't see anything new about it
That x4 thing on the other hand is kinda interesting. Single HDD vibration mounts cost too much for multiple HDDs, but that one probably is less than two of those stabilizers. Edit: infact if the price is right I'm buying one of those. I like my ziptie patent, but 2 HDDs with it takes about 6 5.25” Bays
