Won’t hold charge
I purchased the s70 on 8/1. The product was delivered so I charged the entire system. The light on the receiver was solid green so I proceeded to use the mic and within 1.5 hours of use the receiver started flashing fast green and turned off. I got home and charged it again and monitored the charging progress. It charged over night and again showed a solid green light after over night charging. I used it again and the receiver died within 45 minutes of use.
