Loved it for 3 hours, but the plug for the power adapter is busted. There is nothing for my adapter to latch onto inside the hole.
I just plugged it to recharge it after I got it, which was the only time the plug worked. Didn't have to force it in, but something must have happened for the plug to break inside the unit. Shined a flash light into the opening, and there is nothing there. The plug must be very fragile.
Hooking up the device to my computer with the USB cable does not recharge either. I guess only cell phones have that feature.
Will email the seller and we will see what will happen. I guess I will be the first warranty test case

Will keep you updated.
Update: Should say the "socket" is broken, not the plug. Thanks to pdurrant for the correction.
