I have tried a few different mobile controllers in my life, and I am very firmly in the modular set-up camp. Two halves that wirelessly connect to your phone but fit snuggly together for carrying around, versus the telescopic ones that tend to be more bulky. Recently I got my hands on the GameSir X4 Aileron, a modular example of a controller, and gave it a test run.
