Worth it!

I have been working crazy hours at home and my hands / wrists aren’t bothering me nearly as much as they have in the past. I have been using ergonomic keyboards for years. This is my first split keyboard and I love this thing! I’m still getting used to some of the wider key spacing (it is better every day). I thought the brown switch would be too loud, but it is perfect! LOVE. IT!

It's pretty great except for one flaw.

It's pretty good. My only gripe is that the Y and B keys are not duplicated. I wouldn't have minded paying slightly more for an option that featured the Y and B key on both sides of the keyboard as I tend to type B with my right hand and Y with my left.

Just does not work well with Windows 11

Worked fine for a few weeks, but since then it loses connection with my WIN 11 PC repeatedly each day, requiring me to reboot. Since I don't like rebooting 5-6 times a day to make it work I think a generous rating iz zero stars, but without that option I'll go with 1.

good, lacks macos support

good build quality, good features, good ergonomics, but customization software is windows-only. keyboard is a keyboard, all the keys will work on macos and everything, but you can't use any of the useful features. I had visions of things like: Programming an M key to launch slack, and the light under it to change color and pulse based on notifications, same with email, etc -- forget that kind of thing, even on windows. It can do some basic light patterns, and you can program any key to any color, but there's nothing I've seen to change lights based on events, which seems like a pretty logical thing to include. There's a big, complicated windows interface that could be way simpler. What would be really great would be to have software for this that ran an active API for the keybindings and light effects, and just let people write their own customizations. Maybe not many people would use it, but it would make this device a lot cooler for the kind of people who would, who also tend to be the kind of people who buy $200 keyboards, like me. Just saying.
