You can find cool products for a very low price there. Of course it reflects in the quality. For example in my case, I ordered phone cases, which at the first sight are beautiful but at a closer insight, you can see the picture is pixeled and some are even slightly blurry. I can't complain though since I bought them for 1 and considering the price I've bought them for, the quality is great actually.
You also have to wait pretty long when you order by standard shopping but when you are a patient person who doesn't have much money to spare and doesn't mind waiting 3 to 4 weeks, then it's perfect for you.
