Mohamed A. Use Ebay or Amazon .they do support the buyer when things go wrong .Avoid AliExpress they are on the side of the seller .their game is simple,often the cost of returning the item with a trackable post from UK to China is 50% to 100% of the cost of the item,so you get stuck with an item that does not work .imagine how many buyers lost 10 to 25 pounds ,I hope not many ! but these chineese companies could be making millions by selling these plastic boxes as satellite receivers and other electronics.AliExpress customer support is awful.I had a similar case with Ebay ,they refunded me.Dont expect a refund if you buy a faulty item through AliExpress.It is a scam .
