## Description

desertcart.com: Keychron K3 QMK Ultra-Slim Wireless Mechanical Keyboard Version 3, 75% Layout Hot Swappable Banana Switch, RGB Backlight Rechargeable Wired Bluetooth Professional Office Keyboard for Mac/Windows : Electronics

Review: Amazing. - Best keyboard I've ever owned. Unlike the base model Keychron K3, these keys have much less of a gap between them, and have a nicer feel overall. It feels looks and sounds like those enthusiast mech keyboards on YouTube with the ASMR typing noises. Specifically the Banana one anyway. This completely changed my mind on tactile (e.g. Brown) switches. Previously I only stuck to Blue because it's consistent and never mushy. But these Banana ones are a whole new level. Only downside is the configuration is confusing. I had to install a Chrome-family browser and use the official "Keychron Launcher" webapp to enable the media keys rather than F1/F2/etc by default. On the plus side it's way more advanced and you can do custom mappings and color patterns.
Review: Awesome feeling in the keys - This keyboard is truly great. Clicky keys that you can feel a solid bump when pressed, connects quickly with Bluetooth. The cord it comes with does not connect through my USB port so wired mode is not an option. I have USB 3.1 and I heard that could be incompatible. Latency is nonexistent for my purposes of typing and coding. And the keys have enough curve to know whether your fingers is centered on them and it reduces typos. You can type faster with this. The keyboard is quite small. ***update**** After having this keyboard for a couple weeks I became unable to use my laptop keyboard as my fingers were being retrained to use this very different feeling one. I can't become dependent on a separate device like that so I had to return it. It would be more ideal with a wrist pad I think. Also the click down feet had too much stickiness on one side and it would always end up cockeyed if I tried to move it forward or backward.
