Great keyboard

I love the typing experiencxe on this keyboard, and the fact that it used hot swappable low profile switches is the best feature, because if I find I need to change from the brown switches it's an easy swap.

Great Keyboard 👍

I’m not a “keyboard person” and have no intention of becoming one. I upgraded from a 22 dollar HP wired keyboard and mouse set.

This keyboard is great. Love it. I don’t understand why a backlight keyboard doesn’t come standard with shine-through key-caps, but thats fine. I ordered those as well and they work great.

Love how easy it was to customise the keyboard with VIA. I didn’t want the backlight key to cycle through all of the RGB effects. I just wanted it to turn the backlight on and off. I also preferred the Delete key to be on the far right, where the backlight key was.

Within 2 minutes I had it all changed and set up how I wanted. It was honestly that easy which was f*cking awesome. (Just make sure you read the WHOLE guide on their site, and you’ll be sweet.

Honestly, can’t fault it so far. Its been fantastic.

What a step up :)

The K3 is my first mechanical keyboard and is a complete step up from my previous Logitech K535 membrane keyboard. No mush and a very positive feel. Typing is easier and faster as you can feel that the keys actually actuate properly. The software to change the keys is really nice and it was easy to give myself an INS key (You should put an key cap for it in the box :) ).
Still operating on the first battery charge after two weeks of programming and game play (Wireless but no back light).
Really happy with my purchase. Great stuff.
