Great Factory Support
I received the pair on 08/13/2021. I had no problem with them and was getting use to them. Today ( 09/22/2021 ) I pulled them out of their charging box and placed them in my ear. One of the units would not work. I could very faintly hear the sound of the beeps as I went thru the programs, but the volume on the one would never become louder than a very faint beep. Tried to contact the factory and have not heard back as of yet.  It quit just ten days after the return deadline. It took some getting use to them and I like being able to control volume and the switching between modes all by the touch of a finger tip.<br />Update: I received a reply from Banglijian the next day and they sent me a replacement which I received in less than two days. The way I was treated and the response time was excellent, thank you !
