UPDATED REVIEWseller reached out to me and sent me a brand new set completely free to replace the faulty one. New batteries and charger work flawlessly now. Hold charge as they should and I have sero problems. Used all of them on full cycles 4 times and they are definitely on par with originals1 original GoPro battery easily outlasts 4 of those... And more.I do have 2 GoPro batteries but needed a charger. Decides to try these since reviews were promising.Unfortunately the battery life is really really bad. They might be defective. I don't know.All I know is that I used both of them from 100% to 10% life twice and the performance is the same.I was recording a 10 minutes video on my GoPro hero 9 and the battery went from 100% to 62%. Same thing with the second one. it went from 100 to 67.So basically I am looking at 30 minutes of footage MAX per battery.As a comparison while using original GoPro battery I can record over 2 hours of footage before it dies. That is not right.Also if you charge the batteries in included case, and leave them there unplugged they will discharge. This makes zero sense as the charger is also sold as travel case.To summarize.You get 2 batteries that have 25% of performance comparing to original and you get a charging dock that will discharge your batteries while you travel.This is not a good deal
