Review on Vidpro PG-6 6000mAh Battery Hand Grip Monopod: A Must-Have for Compact Digital Cameras, Camcorders, GoPro/Action, and Smartphones by Crystal Barnes

I tested it two ways. The first method was to use the battery free stick in my Gopro 7 and it worked great. There was no hum that others are reporting. I then tried it with the battery in a Gopro 7 and plugged it into a flash drive and it recorded again with no noise when I played it on my computer. I did notice a slight smell/odor coming from the stick after using it, but I don't think it was a burning smell. It was more of an ozone smell, like using something with a battery. So I'm pretty sure it's a good product. I was a little apprehensive about some of the other reviewers but decided to take a chance and I'm glad I did. I will let you know if anything changes.
