Keychron K1 RGB Hot-swappable Tenkeyless Layout Ultra-Slim Wireless Bluetooth/Wired USB Mechanical Keyboard for Mac Windows with Low-Profile Keychron Optical Red Switch Full Aluminum - Version 5

Red keys are silent as expected - good for office. Take note that tactile feedback not as good as Brown or Blue.

Good connectivity, but keys are far too sensitive. Constantly pressing by accident.

Bought this as a replacement for my old keyboard in the office. I am using K1 v4 at home and decide to get another as it was on offer. This is still the only low profile keyboard I love and comfortable with. The only diff is this is RGB and interchangeable. Keys are quiet which I love. Delivery was fast and was bubble wrap to protect the box. The only thing why it is only 3 stars is I believe this has been in the shop storage for a long time as I can smell inside the box has the stale smell. Their first release date Sept 2022. So this stock should be at least 8-12 months old. Although there is still the regular 1 year warranty, I hope it will last as long as my V4. My K1 V4 bought in 12 November 2020 and still going strong! I will do a follow up update 6 months later. Everything seems ok so far. Will be testing the battery life to see if it last according to manufacturer’s claim. Keychron is one of the trusted keyboard brand which is a no frills and very clean keyboard. The weight of the keyboard is what I love most as it stays really still as it’s built like a tank!

I love the low profile of this keyboard and the RGB lighting is nice. I did end up switching to the banana switches, so I am very glad this has the capability to swap switches as I did not like the red at all! My only complaint is I wish they didn't use proprietary stabilizer design so I could use different keycap sets. But at least the keycaps it came with are fairly comfortable to type on. 4.5 (rounded up to 5) out of 5!
