Don't return this to China!
I bought one of these on ebay. After the initial set up and entering in a lot of personal data it wouldn't power on anymore. The seller wanted me to ship it back. Watch out they can use your data to steal your identity or mask their internet crimes using the data found on the computers memory. I got a full refund from Ebay and didn't have to return the tablet. Do not return after you've entered in any personal data you may get hacked in the future.
