I have not been able to test the product because it has just arrived, what I have been able to prove is the lack of interest in helping customers. The placement instructions in a video in Chinese I do not speak or read Chinese, but I do speak and read and write Spanish, English, French and Italian. It also does not include instructions on how to adjust or tune the device or what spring comes from the factory, questions I asked and were not answered. I contacted the seller but he pretends not to understand or does not understand when he is asked for instructions or details of the device. This is the final straw. My experience with Ali has been disastrous in recent times and it is not a pandemic problem, it is a lack of respect, interest and responsibility with clients.
Good product, well packed, great service. Thanks
