I have not used the keyboard yet! I bought it as a gift for my girlfriend since she's taken a couple classes and wants to be able to practice on the computer a little bit. But it arrived very promptly and undamaged. The keys are printed on very clearly, the letters and Japanese characters pop very well and everything is easily distinguished. I took Russian classes in college and at the time, I bought some stickers for my keyboard to incorporate the Cyrillic alphabet in my typing, but they didn't last long and were annoying to set up. This is a much cleaner solution.I opened the box to see if it came with instructions (since I suspect she'll need help setting it up) and I found them, they seem fine but they also look like they've been translated from another language rather than typed in English (so things are worded a little strangely, but understandable). Also, it covers installation up to Windows 8, but not Win10, so it needs updated. I know the process is similar, but Windows 10 changed the language installation options a lot, so to a less informed user it may be very tricky.I'll try to update the review once we've set it up and she's used it a little.
