Worked fine in A7R V
Price at time of review was £59 with the time-limited option of a 10% discount, so price comparable with other supplier and much cheaper than Sony OEM of course.
The batteries are supplied with clip-on covers, not something I've seen before, so grit or dirt can't get into the battery contacts. The batteries fitted fine into my Sony A7R V; I've yet to see the camera warning about performance limitations with a non-Sony battery, but can't be sure K&F have completely prevented that.
Charging rate was typical, with the charger showing LCD progress bars. I appreciate that the charger has USB-C as well as micro-USB.
All in all recommened to give spare batteries for extended usage time of a Sony camera.
