Great controller and high quality product. Definitely compares to the quality of a Nintendo Switch, but the iPhone/Backbone version which is great for playing certain mobile games, or in my case Playstation Remote Play on a mobile device. The software also really adds something to the controller functionality that really makes it "feel" like you're using a portable console. Overall, I'm very satisfied with the device and think very highly of it. While I understand the decision, not being able to use an iPhone case with the device would be the most minor convenience issue if you have a case that's not very easy to get on/off since it's an extra step that a lot of people will run into when using this device, but it's a minor complaint to a generally great product.
