Review: Great keyboard, but not for beginners - TL;DR: I REALLY like this keyboard, especially once you add different switches and keycaps, but it didn't work out because my accuracy sucks. Definitely not for beginners. Long review: I got the optical reds with this keyboard and it's definitely not for me since I'm a heavy typist. It's just too sensitive so I got the orange and bananas (yellow) optical switches to try them out. I do like the oranges but the ping on some of the switches is too dang loud and annoying so I settled with the bananas (yellow). Once I got them to my liking, it's time to test drive the keyboard. I'm not a typist per day but I can type. Not 100% accurate though, and that's where my problems arose. When I do make a mistake, I will almost 50% of the time would hit the "page up" instead of the backspace.. I do use "del" a lot as well and would hit the light switch instead.. If you're competent and have 99% accuracy when you type, it may work for you. Otherwise, get the K1 DE (what I did instead).
Review: Disappointed Returned after 50 days - Likes - it looks good, it's a beautiful keyboard - the key cap light patterns are very pleasing visually Dislikes - only consistently functional using a wired connection - the bluetooth takes at least 20 seconds to connect to my M1 Mac Mini which is a big breaker for me as it delays my workflow - the red switches are a nightmare to type on, alot of errors - I would exactly call this a low profile keyboard Overall - Youtube got me again - Not what I expected at all - This is my first mechanical keyboard - Cherry Red switches - I decided to try it out, buying it during cyber monday - After 50 days or so I can definitely say this model is not for me - Not very comfortable for my wrists - I switched from using MX Keys Mini the previous 10 months - I purchased my son the SteelSeries Apex 100 Gaming Keyboard with blue switches for $27 and even thought it's wired, it's gives me a much better typing experience - I may try another "low profile" keychron with blue switches but I am worried about the bluetooth connection

### ⭐⭐⭐⭐⭐ Well Made quality keyboard
*by F***® on October 5, 2022*

Had Logitech MX Keys that started to develop some sticky keys. Tried the Logitech Mechanical Mini but didn't love the feel. Got this keyboard with the linear reds and it feels awesome. Will experiment with some of the other switch profiles since these are hot-swappable which is a big plus. This keyboard is more than 50% cheaper than the comparable logitech and just as well made.
