Yeah you are right, just got a response from the seller on Aliexpress:
Kim Gates: Hi dear friend,
thank you for your message.
usually we provide one year warranty, and will help each buyer to use the printer well,
so there almost nobody will do the return., for the return shipping cost is very high,
if you really can not use well, and want return, we can accept
but the aliexpress rules is the buyer to bear the return shipping cost

I'll be getting it Mid August, will definitely post in here when I do, if it doesn't work out, I will go for the HE3D for sure. Thank you very much!
