One of the battery in the pack was dead within 45 days. The other battery depleted very quick. However When I reported this to K&F customer service promptly reached out to me offering to replace the unit at their cost without asking any questions. This shows K&F is trying their best to address customer concerns. My request is to ensure QC on their products to keep their brand reputation.

This is a great buy. Two batteries and a charger for my kit at the price of a single Sony battery. I couldn't be more pleased.

The charger works very well, not fast but solid, it has both a USB C port and a Mini USB. The C port is a real plus. The batteries have held up to all day several hundred photo shoots so far so good.

The is a great value for the money if you own a Nikon Camera: I have owned several Nikon Cameras and one of the biggest issues I have always had is the charger going bad! This charger was one of the best replacements I have every purchased!
Quality: The build quality is pretty good: The plastic feel is somewhat on the light weight side, but it feels sturdy enough to endure constant transport and on the go use!
Performance: The charging performance is okay compared to the original Nikon Charger. This charger takes about 90 minutes to 2 hours to fully charge both batteries! The Original Nikon Charger took about an hour to fully charge. Not a deal breaker for me.
Battery Life: The battery life is really good for these to be after market batteries! I was able to get through two separate photo shoots without having to recharge either battery. That is pretty impressive during a 4 hour shoot!
Great option for aftermarket Nikon Charger.

Just bought a used A7RV and only came with the original battery. Purchased this as a second set, as I usually need at least 3 when I'm off shooting. Batteries charged up perfectly and the charger turns green when the reach a full charge. So far, life seems as good as my original Sony. Good purchase!

They work really good in my camera for being 3rd party. I will 100% be buying another set for just incase reasons.
Edit: So I definitely ordered another set and here's why.
No 3rd party battery warning, it gives me the battery percentage number all the way until the battery dies. I've tested it on all 4 of my K&F concept batteries in my Sony A7iv.
The best part is on a full charge in "basic" 4k mode you get 2 hours of continuous filming with the Sony battery ( $85 or so each) but these K&F batteries will get you 1 hr and 52 minutes each and you get 2 of these battery and a charger for $50. 10/10 I recommend!

These normally are expensive but this charger set pairs great with our nice camera. I like having extra chargers so we are never out of battery when it really counts.

Any photographer knows the first rule of cameras: the battery will run down just when you need it most. So extra batteries are a must, especially when using DSLRs to capture video. I get about 30 minutes of reliable recording time from each battery, so I keep half a dozen charged for any given event.
This collection of two batteries comes with a charger where the two included batteries can be charged simultaneously. That is important. It powers from a USB connection - super convenient for almost any venue and cars where you already have your USB adaptor in place.
The charger has red and green LEDs for each battery to indicate when a battery is fully charged. Super reasonably priced for getting both the batteries and the charger!
These gave about the performance I expected. So a good choice!

No issues what so ever. 1 charger and 2 batteries. It shows if it’s charged or not charged. Does exactly what I need it to do.
