Mine showed up today, seems to work okay but be warned the only way you are getting any kind of wireless controller setup is via new controllers with bluetooth. My one year old Xbox one controller won't work, and you cannot even plug in the USB wireless adapter and use that. You have to actually plug the controller in like we did in the 90's. I guess for $15 it's fine, but it's pretty disappointing that Steam omitted support for one of the most common controllers on the planet.
