Great value compared to genuine Sony batteries. Really pleased with the charger as well.

Having recently purchased a new Sony A7RV, I was looking for another battery. I came across these by K&F, and having had other products by K&F, thought I'd give them a try...especially as 3 of these these come in at almost exactly the same price as a single Sony battery.Absolutely perfect! Despite being third party batteries, my camera (which has the latest firmware), didn't display any errors or warnings. Battery life and build quality is as good as that from Sony. I really like the triple charger as the charge for each individual battery is shown and you could potentially charge everything from a high capacity power bank if you're on the road away from mains power.I haven't noticed any difference in shooting time - everything is absolutely on par with Sony - so I'll very happily recommend these to anyone who uses NP-FZ100 batteries.

Seem to be excellent and well worth the money.

I've been using these for 3 weeks now shooting on my fx30 and I quickly realised they run out faster than my authentic sony batteries, when my sony battery is on 50 percent, these are on 25% so expect these to run down fast.This is a good value for money as a cheaper alternative with the charger but bare this in mind when buying.It functions just the same and it's the same size as the normal sony batteries.Just wish I would of knew what I did now, still 3 pairs will get you through a shoot so it's fine.

Must have additional batteries for Sony camera when doing longer day shoot. Charge lasts long. Charging station is also of good quality and shows the percentage of battery being charged.

The batteries charge well and there is no noticable difference in the functionality from the OEM ones. They function as expected and are a great value for money for this three pack.

Be careful of products compatibility.

I had no idea how expensive batteries were until the one that came with my camera kept dying on me suddenly (really annoying when trying to film!) but to my luck i found this little pack of batteries and a charger and hands down best investment i have made for my content creation. So cheap as well!
