Good products and bad ones too. Something was delivered to me that didn't work. First, you have to wait two months to receive it. Then you have to contact the seller. He asked me questions for 3 weeks telling me how to make it work. I proved to him that I knew it perfectly and told him it was not working. And each time, he told me the same nonsense. I understood that the answers were probably already programmed. So "the robot" keeps you going around in circles for weeks. And when you finally find out how to complain to the management of Aliexpress, you can't anymore because the deadline has passed! So, no need to hope for anything. It's good to know. No?
