It should as long as they have the same MX stem

They are pretty good, tho similar to one of the reply here: last time I used one of their keyboard it was around 2016-2020.

So I’d assume the model with little to no bells and whistle should be reliable enough, even right now.

Oh, that’s rather unfortunate :(

Here’s hoping the replacement works swimmingly

Im not too familiar with STM32, but I think this should apply on all QMK-based device: is the default program still accessible after you disconnect then reconnect the device?

If the answer is yes, then your keyboard is probably fine. That said, I am afraid I can’t help you past that.

Add: If you have access to Discord, you might want to hit QMK Discord server and see if there are any community member that can help you with the issue.

Oh, adding to that: lubing usually helps, although i dont think it’d be the exact same thing as the one you already have on your previous board.

The somewhat complicated (but personally feel the best) solution is to desolder the old switches cleanly enough so you can put it on your new board :D

Most probably due to usage.

There’s also a non-zero chance of it being caused by a different manufacturing batch. The newer MX might still be a black switch, but there might be some changes (be it update on switch design, different manufacturing method, etc.) between version that effects how it actually end up feeling and sounding.

I’m pretty sure its not due to it being soldered, as I got 2 differeng boards with the same type of switches but different switch connection between them and they both felt similar.
