I have an Asus Transformer pad. I bought it brand new 2 years ago. I charged the battery andturned it on. It turned on one time. I tried to turn it on a second time and couldn't do it. I sent it back to Asus for repair. They claimed they repaired it. I got it back and tried turning it on after charging battery. Again..went on but wouldn't ever come on again. This unit was obviously never checked out for qualify control. I never used it. Not even once! What a total ripoff! I will Never buy Asus again.
