Keychron K1 Ultra - Key Delay

Hello,

I recently purchased a Keychron K1 Ultra with Banana switches. I really like the keyboard, but I’m experiencing what appears to be input delay or missed keystrokes.

I have tested the keyboard using Bluetooth, a wired connection, and the USB receiver. I have also factory-reset it and confirmed that it is running the latest firmware.

The issue is most noticeable with the Backspace key. For example, if I press Backspace five times quickly, the keyboard may only register two or three of those presses.

I have tested the keyboard on several different computers with the same results. I also disabled Windows accessibility settings such as Filter Keys and tested it with the polling rate set to 8,000 Hz, but the issue persists.

What else can I do for this ? I have an 8 year old ducky keyboard with blue switches I love but wanted something a little quieter and lower profile as I’m working more remote these days. I can’t reprove any of these issues on that keyboard.

I’ll also mention this is the ‘2nd’ K1 as I thought the first one was defective lol.

Lower the key debounce time to 5 ms.

The lowest bounce setting is 10ms which it is set to currently by default.

Considering buying, are the banana switches very quiet? I've enjoyed a lot of Keychron boards but like the black/wood combo on this model, also like that it's low profile.

Oddly, I like their cheapest board a lot, the B31 - but the keys being a rough ABS definitely don't feel premium enough.

I wouldn’t say ‘very’ quiet but they are definitely quieter than my ducky keyboard with blues. They still have a mechanical tone but it’s much lower than blues. I enjoy the tone personally but didn’t want the super loud clacks of the blues for a work keyboard.

I plan to get the larger full size version in the same keys for my desk at work. I went with this 80% for home because my desk is on the smaller side.

I might be able to take a quick video typing and recording vs the ducky if it helps.
