Nobody QC’s them anymore. They are a good little board, but one thing to realize is they are made by a guy in China who recruits everyone from his Grammy to kids to solder them. They are designed to be minimal cost, and those Jsf connectors are more built for RC than anything. They are also designed for a Chinese audience, which mostly uses them for fight sticks. Red China never caught pac man fever. That means instead of maximizing on buttons and possibly getting them as 2p boards, they have a stupid hat switch and no flexibility with the cable options. Getting QDs that fit a cherry switch was already a hurdle to bringing them to the US.
