I recently upgraded from my Leopold TKL with Blue switches to Ducky Shine 3 TKL brown switches. To my surprise, not only does it look visually pleasing, it's built very well too. It was a smart move for Ducky to get the higher quality dual layer PCBs.
This may sound like a dumb question; but when do the LED's turn off? It would be hard to imagine Ducky would just let the LEDs stay one 24/7 on PCs that don't go into hibernate/sleep. I read the small leaflet manual it came with; but didn't see anything about sleep mode. I also searched online, but couldn't find anything about this (which is a bit surprising). If I could control the LED's via Windows, I could write a small app that takes care of this; but, I'm not sure if the Function key is accessible via Windows.
