I have had two Neewer and two BM (Big Mike's) LP-E6NH batteries for about two months. All are recognized by my R5, and registered in camera with S/N, all allow the green H+ mode. I don't see any real difference in day-to-day shooting with them, they do not seem to drain any faster than the original Canon battery. I have seen some online sources complain about the long-term life of third party batteries, so I guess that is something I will have to look out for. Right now they give me the extra battery capacity for longer sessions away from home.
