COOLSHOW HERO 10 Battery Hero 12/10/9 Battey Replacement 2 Packs and Dual USB Hero 12/11/10/9 Charger Compatible with GoPro Hero 12 Black,HERO 11 Black,HERO 10 Black,HERO9 Black

Two batteries, which genuinely do seem to be every bit as long-lasting as the official Hero 9 one (which isn't a high bar to clear, but hey...), and a great little charger which I am sure is much faster to charge 2 batteries than the camera charges 1. Simply put, it's an excellent deal - couldn't be happier!

Defective product. After sending back to Amazon, no refund !!! Fraud

Good backup

If you have a hero this is a must have! Having two batteries is amazing, wish I’d bought this sooner it’s gave me so much more filming time when I’m out and about rather than having the one battery.. means I can travel for longer without having to stress about how much I can capture of my journeys.The batteries last roughly the same as the original ones, and it also works for the original battery too!Highly recommend if you record footage a lot.

Nothing to dislike.Works just as well as GoPro original batteries with same life.

Adequate for a back up power source, much cheaper than genuine but I'll be saving for genuine in future,these won't do on a long trip unless you charge them often

Great product, great quality, excellent price.

Ok, they do the job.Cheap n cheerful, but dont hold charge that great.But take both out with ya and keep an eye on power left.UPDATE: 6 months on, and these hardly hold their charge, very disappointing.
