...in the US. Other countries have stock.

As a resident of Germany, I disagree.

Yeah I'm pretty sure there's no stock around in every single region, at least according to this: https://www.steamhardwarestock.com/history

Note that they don't check every second so they might miss some smaller restocks (or really orders which got closed and resulted in a few more units being re-added, since the actual stock is fully gone).

I've been trying really hard to get this new Steam Controller, I've been dreaming about playing grand strategies from my bed on the TV, but using a mouse in the bed is awful! This controller is essentially made for me. No luck so far at all the last few days, despite spending quite a few hours checking every few seconds! Region is also Germany. I've given up until the next restock Valve has announced will come "soon", but I'm guessing I'll miss it because there's too many bots aimed at their store page, not even sure why to be frank, are there really thousands of people willing to spend 3x for a singular controller, even if it's a nice one? The market seems to indicate that.
