You know whether a keyboard is going to work for you in the first hour, and having used this one for the better part of the afternoon, this is the one for me. Upgraded from a slim Logitech K380, a great keyboard in its own right, and the audible reaction of hitting the K1's keys is a definite improvement.
UK-ISO layout Keychrons are hard to come by, so I was delighted to find KeyboardCo had this one in stock. The service was great, dispatched the day after the night I ordered, in my hands within 48 hours.
Really happy with the purchase.
