While at first the batteries were working relatively "okay" (obviously less than the official ones, but satisfactorily). After about 1 year, they no longer work at all and in a strange way that even the camera doesn't recognize them anymore.
I want to emphasize here that their use has always been the same as the ones I have from the official company (I used them cyclically). Furthermore, their use has been generally very minimal because in the end I used the camera 3-4, maybe 10 times (exaggeration) during that time, so I suppose they would have died earlier, while I want to emphasize again that the original batteries work just fine.
So, can you trust the Chinese in something so important and sensitive?

Only my charger I like to tell the truth, but after all this, do you trust the Chinese or not?

The battery stopped working after six months of use. Charging is very slow, and the indicator lights are all over the place.

It charges regular batteries perfectly.
Its own ones are okay, for commercial batteries, although they don't last as long as the originals - which is expected.
For the price, it's just right.

The purchase was made in early January 2022.
The performance seems to be around 90-95% of genuine batteries, the charger is quite convenient because it has a slot for 2 memory cards inside the lid and it charges all 3 batteries, but I don't know if it does it simultaneously or if it prioritizes the battery with the highest charge like the genuine charger.
It requires a little attention during charging because it seems to me that the yellow LED has a greenish hue and deceives the user. The green LED is quite bright and just requires patience until it lights up, but it stands out. When all 3 batteries are charged, the charger seems to turn off by itself.
The negative aspect is that in 4 months, one of the 3 batteries completely stopped working with minimal use (5-6 charges).

The charger accepts a maximum of 5v 2.4A, which is equivalent to 12 watts, for all 3 batteries simultaneously. It takes approximately one and a half hours to charge all 3 batteries. The batteries hold at least 10% less charge compared to the original ones. The GoPro recognizes them as authentic.
