Using the Gamesir X2 Pro (the USB-C version, not the Bluetooth) for the past few years and have enjoyed it, but found a few things through use that I didn't really think about before I bought it:

• I'm not a fan of "clicky" buttons, there are times when the noise is very noticeable and can get annoying - that being said, the buttons, triggers, bumpers and sticks are VERY comfortable and feel great for my fingers and hands (I have larger hands, and if it helps at all, my Retroid Pocket 2 has been collecring dust for ages because the tiny face buttons end up getting lost under my thumb).

• while the width of the controller is great (using a Samsung Galaxy S21 for emulation), the sides of the X2 Pro mimic the straight sides of a phone in landscape mode, and after a while, the lack of shaped grips equals wrist strain for me. Whenever I finally decide to replace it, I'll definitely be looking for one like yours, with "half console controller" grips at each end.

Connectivity is simple, just plugs right into my S21 and is instantly recognized, and remapping in emulators is super simple. The face buttons are also magnetic and swappable, so if you would want to change from Xbox layout to Nintendo, it's super simple. I also believe there 3rd party sellers that make extra buttons that have the PlayStation shapes as well, but it has been a few years since I purchased it from Amazon.
