I initially had problems getting my hands on one of these. I was visiting the USA and decided to be clever and order it for while I was there. For whatever reason the product never got shipped, so we were off to a rocky start! However... On return to the Uk, I was able to source one from a local supplier. And I have to say, wow. The experience is seamless. Plug the phone in and away I go. The app store/console app is fluid, responsive and just works. The button to take you there and back just works. I'm not any kind of expert gamer. I have an Xbox controller at home. This feels similar, is comfortable and I haven't noticed any kind of issues. The games play well. Thumbsticks and buttons behave as I would expect. Because I have a phone contract with a 5g provider that allows me to use unlimited data because I buy my Xbox unlimited through them, I can game on the go, at better speeds than my home broadband. I am definitely a happy boy with this. Highly recommend.
