I'm in the same boat pantsqueen & schwingaway... mine also just arrived and besides it lighting up (and immediately going out), it won't do anything. It won't type, can't find anything online... www.kc-keycool.com is non-existent as far as I can tell. Please respond here if any of u guys find out anything, I'll do the same. Thx
jo3m4m4Mine arrived with what appears to be a defective USB cable. When I first plugged it in, it behaved the same way as you report. I tried with an old cable I had home and now it works fine. Maybe you tried that already, but I felt it was worth mentioning.
jo3m4m4Wanted to clarify, my KEYCOOL KC87 works great, all aspects I've checked and use regularly anyway. Love the Bluetooth and RGB options on the KEYCOOL. This and the SmartDuck XS87 are awesome keyboards! Awesome enough I would buy each again if/when they die.
