This is unsolicited feedback, nobody asked me to write it. I wouldn't bother leaving feedback here, but I got angry at seeing "F" rating by Fakespot justifying it with "insufficient reliable reviews".
OK, this product is true innovation. Something that a seemingly unrelated Chinese company has done notably better than the companies that make original cameras and lens. It is rare but it happens. Kudos to K&F, you rock!
I am throwing away old batteries and chargers and replacing them all with these!

One of the few 3rd party brands that doesn't trigger battery warning msg with my Sony A7R V camera (firmware Ver. 3.00).

I just tested with my A7 IV firmware versions 3.0 and 4.0. No warning.
So far so good.

After testing them for a few weeks, I have to say that their lifespan is a bit shorter than the originals.
The good thing about these batteries, unlike other non-original ones, is that these don't give you the "non-original battery" message.
So, for now, they're perfect for my Sony A7M4.
We'll see how they age.
