If you have prime, you get 5 free games a month on Amazon Luna Subscription or pay 9.99 and get a larger selection plus also stream a majority of Ubisoft games that you may own. By far the best quality and reliability streaming service of which there are not many around.The controller itself is a good size and fairly comfortable with excellent grips, doesnt slide in the hands like xbox or ps. It is easy to put into bluetooth pairing mode and works well but the trick up its sleeve is the awesome inbuilt wifi receiver, its game changing! The amazon luna service is available as an app or web page on pretty much any device, if it can stream the web page the controller automatically connects to it once turned on its brilliant. On your PC, on your tablet, on your TV, on your Tesla.Tesla made it awkward to connect a controller to its newer cars until bluetooth support becomes available, but stream Amazon Luna on the web browser in the car and fire up the controller and away you go!Cons: Only few gripes are buttons are a bit firm to press, at the moment there is no replacement battery charger pack (just use a AA battery plug in charger) and the price. Its not cheap but to be fair its like two controllers in one, you may never need anything else and the technology is unique and just works out the box and you can wait for an Amazon sale. One controller I ordered did not work correctly but another positive of this Amazon controller is the usual Amazon service applies meaning replacement sent out asap ?
