I have been lurking here for a while and I wanted to warn everyone about dealing with alibaba and particularly the seller "digital deals". I purchased a zt-180 from them a few months ago. 2 months after I puchased it the internal charging port broke off of the board. I contacted the seller and he told me to send it back for a refund. I really didn't feel comfortable with this arrangement but didn't have many alternative choices plus he told me to "trust him". I sent the tablet back to China and waited for the refund. Guess what - no refund. I contacted digital deals several times and have not gotten a response. I contacted alibaba, which is apparently similar to a chinese ebay, and they said that they can not do anything because it is out of thier 45 day "return window". I have also contacted paypal and they can't do anything either. I am now out the original amount that I paid ($216) PLUS $40 to ship the thing back to China!! BEWARE OF THIS SELLER!
