The K2v2 is a great keyboard that's a pleasure to type on with the Gateron Brown switches. These switches offer satisfying tactile feedback and aren't too noisy.
I'm a software developer, and have found that this keyboard is the perfect balance of being compact in size but still providing all the keys required for writing code efficiently (home end, arrow keys, delete). It took me only an hour or two to get comfortable typing with the majority of the keys on the K2v2, however after a week I'm just about getting accurate when hitting the home end keys to the right of the return & up arrow keys and the delete key (above the backspace key). I'd say once your muscle memory becomes familiar with the key positions that it's a dream to type on and doesn't feel at all cramped despite the compact footprint.
The keyboard comes with spare keycaps for Windows Mac, plus grey versions of the accent keys (esc and the backlight key, of which there are also included red accent versions). Also included is a USB C to A cable for charging (or non-Bluetooth usage).
I'm using it via Bluetooth with my Surface Pro (Windows), it was seamless to connect and I've had no issues with connectivity since.
I love the monochrome aesthetic having switched out the accent key caps for the grey ones. There are some very funky backlight patterns including ones triggered on keypress and more passive ones such as a gentle wave effect. There's also the option to adjust the brightness or turn off the backlight completely.
There are only two small issues that I can find with this keyboard. First, when plugging in to my Surface Pro to charge, the laptop complains that the keyboard is trying to pull too much power, and disables the USB port. This is a minor inconvenience and I've opted for charging in a USB plug socket instead. Second, for other Bluetooth devices I own, the battery level can be seen in the Bluetooth & other devices Windows settings screen. This is not the case with this keyboard, however the small battery indicator light does flash when the battery level is getting low.
Overall, this is a lovely and compact keyboard, and those minor niggles don't budge it from five stars. Thank you to The Keyboard Company!
