From flagship smartphones to VR headsets, first-party accessories tend to be pretty expensive. Along with the higher price tag though, consumers typically expect exceptional quality. After all, the product’s designers had a head start, so those day-one accessories should be, if not the best out there, at very least high quality. Meta sells an array of useful accessories to fit that description, although some of its most expensive first-party stuff—namely its Elite Strap—continues to face reliability issues even today, as many users of the Elite Strap with Battery for Quest 3 are reporting faulty units.
I dunno, some people find the influence and data they sell to be useful.
