I had searched a while for a good controller solution for my iPhone so I could stream games from my PC or play controller-supported games. Backbone does everything I wanted and more. It's comfortable, easy to use, and has a really useful software suite that gets me right to my controller-supported games and console remote play. It even adds a headphone jack that doesn't require lightning cable headphones so I can charge my phone and use wired headphones at the same time. The Backbone is just perfectly engineered. (This is so glowing it sounds like it was written by their marketing team, but I promise I am a real customer that just loves this thing.)
