I have a Quest 2. After 6 months the non-replaceable battery lost 70% of its capacity and the controllers developed unfixable drift. Never making the Meta mistake again.
It's definitely fixable, by both Meta and yourself [1]. I've done it twice. A replacement kit is $14 on Amazon.
You would think joysticks would be a solved problem by now, but no. Meta chose garbage, with the same garbage installed in the quest pro controllers that are not really serviceable, from being glued together and jam packed with electronics (3 camera inside out tracking in each controller).
Battery can also be replaced, but with somewhat ridiculous effort [2].
