I have shopped from Aliexpress.com and it is a hit and miss. You have to know that this site is like a big mall with hundreds of shops some are good some are bad. I have a complaint against a particular vendor: http://www.aliexpress.com/store/contactinfo/*******.html
Do not buy anything from this store. They are fraud and you will not receive anything from them. I will file a claim with Visa and Paypall, because with aliexpress dispute I reached nowhere! Do not buy from this shop. Nior Jun is the "person" who is the contact and I guess the thief..
