This is my second order of K&F Concept batteries, which shows that I was satisfied with the first order. I take hundreds of pictures every day and really punish batteries, and these have stood up well, lasting as long as the original Sony battery. They are completely compatible with the camera, unlike some cheaper replacement batteries that lack some vital feature and cause the camera to put up a warning notice.

Pretty standard replacement batteries and charger, nothing crazy. The batteries are keeping up with the original ones pretty well, I haven't seen any differences between them yet and I've been using them for a couple months now. Absolute best thing about this is the dual input, it can take either Micro USB or USB-C, which is super helpful for me. LCD screens seem to be accurate. Even if the batteries don't last a super long time, I will definitely be buying these again just for the value at this price point.

I bought these batteries to go with my new Sony A7 IV camera. The battery life is a little shorter than the Sony battery but it is otherwise great. I've been told that some batteries can cause a warning to pop up on your camera. I didn't have this issue on my A7IV.

Excellent value for money, battery life not as good as original Sony but for the money I’m very happy

Buy these batteries with some fear since they are not the originals and the camera in question the sony a6600 is worth a peak, but they are going very well, they last less than the original but with the price of these two I can't even buy an original one, so between the two charged batteries I have more time to work.
For now they work perfectly.
