I haven't found a way. I too used days of research, going to a physical store to try something when possible/applicable, YouTube reviewers, many many websites that used to be trusted, plus Reddit reviews. They all lied, or maybe I'm doing something odd to cause my own problems? Or both:-).
And even when they did not lie, about their past experiences, in one case the company itself ended up betraying its entire userbase so bad it made an international sensation and the cofounder left the company in protest - OnePlus I'm looking at you regarding the 7-series updates. I will never purchase a OnePlus product again in my life as a result, which is doubly sad bc nowadays they once again seem like good devices, and triply so bc I know of nothing else remotely like those "flagship killers" of old - that whole genre of phone is just over now, and they were merely the last hold-out.
You have to somehow be an expert in every little thing these days, and when you do find something you may want to consider purchasing more than one of the item to avoid having to go through all that again when the first one breaks, if that makes sense for the situation (for a keyboard I dunno?).
If only after doing all that you could share what you found with family+friends, to spread the love and avoid the same pain all around!? But in reverse, would you trust the reviews of your family members & friends - how sane are they, when it comes to this stuff? We want reviews from people better equipped to do so than we are ourselves, not average or below:-).
Which is why I'm saying that depending on the cost you may want to just roll the dice and see, and also expect to spend even more days of research, and also go back through historical archives of Reddit forums as much as possible. The goal of all capitalism is to take your money, period. The likes of Amazon and Google have truly enshittified the act of internet commerce:-(.
