UPDATE: seller provided a udev.rules file that resolved the Linux issues: https://dl.sayobot.cn/udev.txt - after setting that up, https://sayodevice.com/ works fine on Linux too.I bought this to reprogram the keys to do other things besides copy/paste. I completely failed to do this on two Linux laptops - sayodevice dot com UI loads, lets me select the HID device, and then nothing. I then tried the Linux binary from the zip bundle. If you can get the shared libs installed, it runs, then it opens a web UI (a different one), and that one can't find the device. Tested all of this with the latest Chrome and Edge (doesn't support Firefox)Eventually I tried it on a Mac and the web UI worked (initially that was glitching too, but it was the cable). So, if you have a Mac, you may be OK.The configuration UI is aimed at programmers - you can write a script in what seems like their own macro language. It's fairly easy to set up basic actions like keystrokes and text/password entry and color schemes for the LEDs. Changes take effect immediately but aren't persisted until you press the hard-to-find save button.In the end, "Linux support" was a dud. If I have to reconfigure this thing, I'll need to find a Mac, again.

Why did you pick this product vs others?:This little keyboard is such a time saver. It's also much more comfortable to use than the two-key keyboard shortcut. Two of my coworkers have purchased one also.

Success! It plugged right into my work laptop without needed IT approval, unlike a keyboard I tried previously. This will save my left hand a lot of stress.

Why did you pick this product vs others?:Copy button works 65% of the time making this product worse than just using the keyboard

No software required and does exactly what it says. 0 complaints!

I copy and paste probably hundreds of times a day at work. So much so that stretching my hand from CTRL to C and V actually starts to hurt after a while. This button, while silly, is my favorite thing on my desk. There isn’t much to review. It works perfectly and lights up. I took a star off because it is supposed to be programmable through a browser but that doesn’t work at all. So I wasn’t able to change the light pattern or change what the buttons actually do. Not that I’d want to, Infot it for copy and paste. It comes with interchangeable buttons as well. You can change them from black to white. And there is a third set of blank black buttons if you are able to change the function from copy paste to something else. If I got it for something other than copy paste aid be mad but it’s fine. 4 stars. Probably will get another one for home. It’s so stupid but I really do love it.

Why did you pick this product vs others?:I have been using this keyboard addition for over a year and it really speeds up my workflow. The customizable lights are a plus too.
