I bought this keyboard package for my son as a birthday gift so he could take lessons. However, after barely 6 months of use, the keyboard has begun to turn off in the middle of play. It is completely useless now and I am going to have to purchase another one.When I went to Casio's website to look into the warranty, one of the selections for reason of return said "Shuts off during play." So I guess this is not a rare issue. I filed a claim, being less then 1-year from date of purchase, but the kicker is, I have to PAY to have the keyboard shipped to Casio. Then there is no guarantee that I won't be charged $75 for repair.I am so unhappy about this and so is my son, who will have to miss lessons and practice until we can buy a better keyboard. And definitely NOT a Casio!UPDATE: We found out that the problem was NOT the keyboard, it was with the power cord. We now only use this keyboard with batteries. Still would not recommend.
