Trojans and walware installed on phone
Order an ASUS X008 from them it took over a month and when it finally came it wouldn't work properly. So me being a bit of a nerd had a look at the OS and found out I couldn't update it, then I did a full system scan and found no less than five spyware installed on it now that's on just a normal scan if I decided to root the phone to have access to the full OS I'm sure I'll find a lot more. Tried to get my hard earned money back and discovered that it's near to impossible to truly to get your money back due to the refund policy, can't use FEDEX/DHL etc., so in short can't ship it with someone who will be able to ship batteries and if that's not bad enough you have to pay custom duty in china as they will not accept it unless you do.
