In which case, Aliexpress is the way to go as that's their official storefront and where I bought mine from. I completely understand and relate to not wanting to buy from Amazon as I'm doing the same, I just know a lot of people prefer to buy from the "local" company.

Those mechanical switches are extremely subjective. I can appreciate the intent of having both precisely physical and acoustic feedback for a button press but I already type on a mechanical keyboard - for context - and when I unearthed that same 90s controller I alluded to of mine that had been hiding in my attic not too long ago, pressing them made me immediately feel the arthritis I'd end up with if I chose to use it full time. I don't mean that as an insult, it's a satisfying feedback but there's just something so aggressive about it too, if that makes sense.

According to the Aliexpress page, the KK3 Max will be released on Jan 5th so give it about another week or two for reviews to be out. I'd imagine you already have someone you like to watch/read for controller reviews but just in case, I recommend Gamer Heaven on youtube. I've found him to be pretty good with descriptions and comparisons when explaining the feel of each product as well as the level of general depth he's willing to go to compared to the usual "this is what it looks like and it feels pretty good in the hand". Like expect latency and circularity stat tests.

No problem, always happy to help where I can and it was good having a nerdy conversation over controllers considering my best friend just brought me much shame by buying a Dualsense when he doesn't even own a PS5 and how much I've already preached about stick drift.
