This is a bundle that includes both a PS4 controller and a USB receiver that allows you to use the controller on a computer. I got the latest model of controller in my bundle (CUH-ZCT2, the one with the light bar on the touchpad). It's a genuine PS4 controller so it's excellent (there are tons of reviews out there for that already). The USB receiver works well, at least it did for me. Windows 10 recognized it right away and I didn't have to lift a finger for it to find the drivers. Pairing it with the controller is a little odd though. you have to push the USB stick in until it flashes and then you have to hold the PS4 controller PS button down for a few seconds until it flashes and syncs up. After that it works just like it does on the PS4. I didn't run into any lag or problems. The only thing is there is no way to tell how much controller battery you have until it suddenly dies. It works great in Steam as long as you set it up with Steam first. It's nice that for Steam games you don't have to use a 3rd party emulator/button mapper. And it seems that if the game supports the XBox 360 controller (I have a wired one) it supports the PS4 controller through Steam. Although, I only have a few games so I wasn't able to extensively test it. I bought this bundle for the controller to use with my PS4 because I was able to get it on sale for less than regular controllers sell for on sale. But now I can use all of the my PS4 controllers with my Steam games if I want wireless.
