Their customer service is terrible! I have asked four times to get a return authorization number for a product that I'd like to return, and it seems they "misunderstand" me every single time. So we keep going around in circles. I will never buy anything from them again. UPDATE: they finally contacted me and told me that they would refund my money less a 20% fee and I had to pay for shipping back to China. Essentially, it would have cost me more to send it back than what I paid for it.
