Big thanks to @YourAppleSalesman (aka @romfighter) for discovering that these were for sale! These can be picked up NIB from http!//www.ebay.com/str/katesgoodies217, which is where I got mine. Surprisingly no mechanical issues, works right out of the box. As always, chinafake Discord, wiki, and other social media (including fediverse and Bluesky) are at http://chinafake.wiki/links
