Warning never buy at Aliexpress.com! Warning, never buy at Aliexpress.com. I bought a defective item - the product did not work. Unfortunately I can not be allowed to give zero stars! Raised a Refund case. Submitted all the documentation they asked me to send. Each time with the result that refund was rejected. Last time I had to post a video. I sent it and Customer Service confirmed that they could see the video and they could also hear the sound. But got the message that the refund was rejected because they could not open the video. When I then again again wanted to proceed with the case through their Customer service, I could not get in touch with them. That's because they've blocked me. They obviously do that when they have no more arguments. This is the first time I have raised a case with them and yet they are acting as a criminal enterprise. I will never support that fraudulent company again and I urge everyone else to boycott Aliexpress
