I purchased a pro controller from a recent deal knowing that it works on PC. But because it is a custom built pc, it doesn't have Bluetooth.
I considered just picking up a cheap random dongle from eBay but after I read bunch of posts online saying that some dongles are not optimal for gaming, i didn't purchase one with the pro controller.
Today, I'm picking up the controller from a local target but i still don't have the dongle for pc.
My budget is about $20 but of course lower is better. (I would prefer it to be under 10 if possible, but performance first)
MSY has a BT dongle on special for $7 bucks atm. I have no idea how good it is.
