At the end of the day, the companies involved in keyboards are still novices in understanding how to appropriately communicate with their consumers (and are still absolutely horrendous in other issues [e.g., avoiding damaging consumer trust through loot-boxes]).

In keebs - you should never build without checking the PCB. Because of the burden of proof that companies in keyboards have, it is in your best interest to record opening boxes when they arrive to verify condition & also test the PCB or other aspects. Keyboard companies WILL deflect to avoid accountability. Novelkeys, while good in some cases, is particularly known for this (e.g., when products arrive that aren't of expectation, they just hit ya with the copium).
