Title: very disappointed
Review: I just bought it last week and am using it on my travelling. the screen can be turned on somtimes and cannot be turned on somtimes. Do not know why. It is not the problem of bettery definitely. I charged a whole night last night, but cannot turn on the screen this morning. when i returned back the hotel and tried again, it is been turned on. I encountered the same problem 3 times. The product have some problems, and makes me very frustrated. I'll return back it to Amazon.
