Loving the keyboard but customer service isn't as good as the product

I love my keyboard and was very surprised how quickly it was delivered as it was shipped from the other side of the world. Still, I messaged the customer services team using the live chat on the website as a discount code I had wasn't applied at checkout and because this has been constantly out of stock didn't want to miss out, so I went ahead with the purchase anyway..., and no one got back to me. Of course, then it was discounted even further on black Friday but that's the risk you take I guess.

Oh and I agree with another review, it's hyper-sensitive!

Dream keyboard, but very sensitive

This is my first mechanical keyboard and I really like it a lot. The build quality, look and feel are all amazing. The only downside is that they keys are so sensitive to input that even resting your fingers on the keys will sometime register as a keystroke, which takes some getting used to..

HOT-SWAPPABLE

We all have our unique typing preferences, that’s why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We’ve implemented a MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.

You can easily hot-swap every Optical switch in a few seconds to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.

Optical Switch

With the MX-styled stem housing and 0.2ms ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a 70 million lifespan much greater than industry standards.

*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.

ALTERNATIVE KEYCAPS

We’ve spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.

It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.
