I started with just a $15 clip for my Xbox controller, but after a couple weeks of that I got annoyed at the awkward weight and holding my controller. I ended up spending the money on a gamevice flex because it has bigger thumb sticks and grips than the backbone or kishi. Still around $100 I think, but it was 100% worth it, if not necessary. I’ve also used my switch pro controller hooked up to my iPad. All of the controllers worked flawlessly, just a personal preference thing and value for $.
