I absolutely love my Backbone controller! It feels excellent and opens up so many options for how I play games on my iPhone. My personal favorite game to play with it is Rocket League Side Swipe. Having a controller makes the game feel so much more natural to control. There's even an app that does a great job of adding games to a console-style menu that you can navigate with the controller! Before I had this controller I would use a grip to attach my phone to an Xbox controller. Not only was this clunky but it also added lag because it was using a Bluetooth connection. I love this thing so much that I even bought a second one for the PlayStation design. However, there is a big downside to the Backbone. While it feels great, I have some concerns about the durability of long-term use. I mentioned before that I bought two. Well, it turn out that I had to send both of them back for warranty repairs. One had a trigger button that stopped working and the other started making a strange grinding sound inside the right stick. To the Backbone team's credit, they were both replaced for free. That said, it doesn't change the fact that you are pretty much required to buy some kind of 3rd party case on Amazon. I originally bought both because I love the product but now I feel like I need a second one as a backup. I also think the buttons feel a little bit too clicky and rough (like a Nintendo Joy-con). I wish they weren't quite so harsh to use but that's just personal preference. Also, one potential downside in the future is that this controller plugs directly into the iPhone's lightning port. This means that if you upgrade to a future iPhone that doesn't fit the case (or if the EU forces apple to change to USB C) these will be pretty much obsolete. The team has done a great job adapting the case with things like adapters that accommodate the 14 Max's camera bump but I worry about how long they can keep that up. I really hope they add some kind of lightning to USB C adapter if Apple does ever make the switch. Overall, despite the issues, this is a fantastic controller case! I have left my Switch in its dock for months because I find myself playing with my phone instead. That is a HUGE change from even a year or two ago. This product fundamentally changed how I use my phone and opened me up to a world of new games. Even with the issues, as long as it fits your phone I highly recommend it!
