All HDBaseT devices are based on the same chipsets from Valens. So, from that standpoint they are all the same. The differences are going to show up in power supplies, the PC board design, the other parts on the board, and quality of fabrication. Low cost products should work just like expensive ones, unless the manufacturer just plain screws up. And, apparently, they do. Kind of stupid considering the most expensive part by far is the Valens chip.
