Good value for the price.
Battery life on my M5 is about 500-600 shots before the red blinking warning starts (my canon battery is 800-900 shots despite what the reviews say). That's with an auto-focus lens and a mixture of screen and viewfinder. (no video) It lasts longer if I'm using a fully manual lens and a bit less if I'm using my 55-200 autofocus lens with image stabilization.
What I love: USB charging! Fast to charge, easy to stuff an extra battery or two in my pack, keeps the charge without having to worry.
What I don't like so much: It doesn't tell the camera how much charge is in the battery until it's almost empty.

Battery changer is very handy, I can charge anywhere especially in my car because it has usb 2.0. Also it can charge two battery at a time is one of most usefull feature. I like the battery charge

Nicely designed with the flat casing, it's super compact and easy to pack which makes it so easy to charge off my power bank when I have it in my little backback. Makes being a tourist even more convenient! The battieries last long in my 7i and I barely notice how long they take to charge since it's so quick and with the two slotter it's an easy no brainer that this is an awesome set!

When I received my order of 2 batteries + charger one battery did not work, it showed as charged but did not work in camera. I contacted KF concept and within 4 days I had received another 2 batteries and charger. Must say first class service.

The batteries work very well, the double charger makes it very effective to have enough capacity for the next day of photography.

Bon produit pour le Nikon Z6III, un bon compromis, par rapport aux batteries officiel Nikon
