Kinesis hit the ball out of the park with this model. I'm a software engineer and spend most days doing hours of coding and typing emails/Slack/documentation; I can't imagine working without this keyboard. I use Karabiner Elements for all of my keyboard layering and remapping and haven't had a need to customize the firmware yet so it's been a great drop-in replacement from the older Kinesis Advantage models I've used over the last 10 years. It's really easy to switch the keyboard over to different systems when you're paired via bluetooth. I have two Macs and just hit Mod-1 for system 1 and Mod-2 for system 2 and the keyboard switches seamlessly. This model proved to be worth the months of waiting for it to be released.
Been waiting for a split version of the Advantage for over a decade and this delivers. I had to move a few keys around and remap them to make it suit me, but once that is done it has been great. The github interface is a little slow, but fine honestly. I've been on a regular keyboard for the past few months cause my old Freestyle died and I was waiting for this. It was worth the wait for sure, but it's taken a few days to get used to it. I'm now up past 50 WPM on it which is only a bit slower than I am on a "normal" keyboard but perfectly servicable. I still have a number is mis-clicks, especially for keys that are in different places like +, but I think I'll be faster on this than on a regular keyboard eventually. The main thing I wish is that each piece had a threaded mounting hole on the bottom so I could easily mount it on a chair (been thinking of actually mounting it so my arms hang down to type for ultimate ergonomics). The icing on the cake for this setup would be to incorporate one of those old IBM nubbin mice, or a trackpad into the board so you could just leave your hands down forever.
Feels so solid and well constructed. The keys take a little getting used to - they require less pressure than I expected based on my previous Advantages - but after day typing on it I appreciated the shorter travel.
I really love this keyboard! I have an advantage2 and love that as well, however the aesthetics of the advantage360 were obviously incredibly appealing to me along with the split keyboard side of things. Currently working on finishing my setup which is quite unorthodox yet works perfectly with these. I have a keyboard tray attached to a kitchen counter (I'm a software engineer who basically just codes nonstop I don't do much cooking lol) and from that I have another smaller mouse pad tray coming off for a trackball mouse. Currently have two more mousepad trays coming which when attached will be able to hold the two sides of the keyboard perfectly, and at the perfect height to allow me to have my hands in as near a perfect resting position as I could hope to get it, allowing me to use my armrests while typing in an extremely comfortable fashion.
This keyboard has basically just perfected my setup and I am beyond happy with it. I got the basic version because I didn't need wireless, even the wired version is trivial to carry around, so I didn't see the benefit there really. Worst case I'll get a second for the office once more are in stock. I got extremely lucky and searched for this on a whim on google and found the Jestik entry there. Happy I stumbled upon it and ordered, didn't expect it to sell out so quickly. I did replace the home keys with my advantage2 keys because they are shaped slightly differently and catch your fingers, but that's a personal preference (I also like the blue on those keys, looks pretty nice with the advantage360)
It blows away the old advantage I got the wireless one and love it!
