I’ll try to concentrate my 10 years experience with AliExpress in several advises:1. Don’t buy ANY EXPENSIVE EQUIPMENT there. They will refuse to refund if it is lost in your country or if delivery takes long time, because their “protection” is gone.2. Don’t buy ANY batteries there, you never get described properties and they will refuse to refund because you are not a “professional tester” of these properties.3. Don’t buy from recently created seller, it’s mostly just fraud, with fraud tracking number. You will wait for your parcell untill their “protection” will gone and they will refuse to refund.
