Review on Dainslef Xbox/Xbox One Controller Phone Mount: The Ultimate Xbox Controller Holder for Phones - Foldable Clamp for Microsoft Xbox One/Xbox One S/Steelseries Nimbus Duo (Clip Only) by Joe Merculief

I am using the clip on an XBox One X Controller with a Samsung Galaxy Note 10 plus. It's a big phone but the clip holds it well, even with my phone in a case. The phone feels very secure in the clamp, and the clamp attaches very securely to the controller. Installation is easy but requires a little effort to fit on the XBox controller. Inserting a phone is easy. The spring-loaded mechanism opens easily and closes securely. I definitely recommend this clip if you use an XBox controller to play games on your smartphone. As a bonus, they include a pair of silicone sleeves for the joysticks on the controller. You're not that bad. The finish on them isn't great, but they fit well and give you some support.
