I’ve had two DualSense controllers for almost 2 years now, and they get heavy use.

Absolutely no problems. Thought one was starting to get drift, but I opened it up and it just had a hair stuck under the stick of the left joystick.

I had a Nintendo Switch for less than a year and every joycon I got (the original 2 that came with it + two additional pairs) all got massive drift issues within a month or two. It was the main reason I only had the thing for a year.
