That's not 100% correct. You can get them if you buy 500 or more. Product page: http://www.speeddragon.com/index.php?controller=Default&acti...

I talked to Syba USA two months ago and they said end of Q1 so I didn't pursue the idea of bringing 500 into the US and sell them. I still might. Do you know any good platforms for this sort of thing?

The other reason I didn't pursue this because the Realtek based 2.5gbps adapters are out https://www.centralpoint.nl/kabeladapters-verloopstukjes/clu... (USB A version: https://www.centralpoint.nl/kabeladapters-verloopstukjes/clu...) and I wasn't sure whether people would care enough to jump to 5gbps.

I put it on Massdrop https://www.massdrop.com/vote/Type-C-USB3-1-to-5-Gigabit-Eth...

Nice!

Unfortunately, I don't know 500 people who'd want one and I think shipping from the US to anywhere not-US (say, Australia) would be prohibitively expensive.

Sorry, no idea as I've never heard of them. :)
