I ordered on 05.09.2020 and I did not receive the product today. The seller asked me to wait another 20 days after the 90-day period expired, I accepted and after that I could not open the dispute. I resumed the dialogue with the seller and he did not want to return my money or send another product. He was not interested in feetback and stated that it is ok, if I write a negative feetback .... In conclusion, if you have problems like this, open the dispute within the established term because otherwise you will not get along with this seller. Bad seller !!!
The product matches the settings. I received after 17 days. Efficiency has not been tested.
