Was after a cheap gamepad for my Fold 4 and came across this. I got mine delivered today and pretty happy with it given these ones normally sell for closer to $30. Works well with my PS2 emulator using the controller wirelessly in Xbox mode. Makes GT4 very playable and graphics upscaling makes it look fantastic on mobile despite being a really old PS2 game. Also works for other Android games (only did a quick try of Asphalt 9).
Seems to also get good reviews for the price.
Razer kishi v1 is around $50
