By now you have already seen the reviews and videos and everything. But the issue I (and many people online it seems) are having, is connectivity to PC via Bluetooth. The controller will connect successfully via Bluetooth, but it is not seen or recognized by any games. Connecting it via cable solves the issue, but I bought this to use wirelessly, and it says in the booklet that comes with it that it works. But it doesn't, unless you use a dongle or cable.
EDIT: THIS ISSUE WAS SOLVED via a windows update. You also need to update your controller firmware using the xbox accessories app on windows 10. You might need to remove and pair it again after the updates.
