Was in contact with the manufacturer to get powercord, headphones and instructions, that were not included in the original package, as advertised, and was told to take it up with 鶹. We bought a proper powercord for $10 off 鶹 so at least we can use it, for now. We only bought a second one because the first unit was so enjoyable for our grandchildren at our vacation home, so we know what was supposed to come with the keyboard. It would be nice to have the original instructions. headphones and a powercord that was made specially for it.
