The batteries work very well, and it’s great not having to trip over power cords or deal with low-battery anxiety anymore. At the end of the day, they’re batteries—it’s a pass or fail situation, and they definitely pass.
However, I do have the same batteries from Neewer, and I have to say I prefer the charger that came with those. Aesthetically, the Neewer charger looks better to me. Would I pay more for it? Probably not. But if everything else were equal, I’d likely choose the Neewer option just for the charger.

With a 900mA discharge current, one battery tested at 8500 and the other at 8800, which is higher than the advertised capacity. Usually, we see the inverse.
The charger consumes 5W for each battery, even with a single battery, the charge is slow. Even with USB-C. This mean 11-12hours of charging time. Charging LED's are inverted compared to battery position. This is not the best charger, but this is accurately what is described.

This a great set of NP-F970 batteries and charger. The batteries work just as well as the original Sony one, costing a fraction of the latter (the NP-F970 is $229 on Sony's website). There is a difference in specs between the two: the Sony battery is 7.2 V whereas these K&F are 8.4 V but they are both rated as 6600 mAH so there might not be a noticeable difference in real-life usage.
At around $70, this set is a good value however it's too early to tell if they last as long as the OEM model. I will update this review if my opinion of them changes.

The battery have no button to check it charge level, and the charger is very basic (but support USB-C).
I've just done a capacity test, and I got 55Wh off one, and 57Wh off the second with a 1amp load. While the battery say it rated for 47.52Wh, so the battery offer more than the advertized capacity, which is perfect in my book. Long term capacity test will have to be done on them in the future, but so far it look good
