After 2 months, the right bumper began to stick. After releasing the key, it remains pressed for about a second or two, it is obvious that it is impossible to play like that. He handled the joystick carefully, didn’t get dirty / didn’t flood / didn’t get anything under the button. I gave it to the microsoft service center under warranty.

I'm surprised that so few people who actually noticed this problem, as the Internet is teeming with similar topics about this device.
