I bought my Keychron V1 Max with Gateron Jupiter Banana switches in late Q3 or early Q4 2024 and couldn't be happier with it.
It works flawlessly and I was able to swap out the switches to Otemu Silent Lime v3s (lightest silent tactile I could find, thought the TTC Silent Blueish Whites were in a close 2nd but were more expensive so I chose the Otemus in the end).
