They’re really cheap. This one cost me only 2800 INR (~$30), but the vibrations are terrible. You can get one from a reputed brand for about 50 USD. I think Razor and Gamesir also sell these.

The only Android game I play with this is Fall Guys, that too once a week or so. But primarily I play PSP and PS2 games. Apps like Retroarch provide a really nice UI for retro games, and can make you feel like you’re using a handheld console. Here’s a screenshot of Retroarch:

NetherSX2 is also great. Here’s the screnshot:

I love this thing and would recommend such gamepads to anyone looking for a handheld console experience.

Here’s a few more photos of this.

Btw, it can also be connected to any PC with a Bluetooth connection. This one can also connect to PlayStation 4 as well. It will work on PS5 too, but only in UI and PS4 games.

PS - Sorry for the blurry pictures. i don’t have a good secondary camera.
