Bought this for my alpha 7iv, have used the batteries without problem. Charges from empty to full takes around 2.5hr. Great to be able to charge two batteries at the same time. Batteries are slightly less long lasting than the Sony original but I would say they are 70%. For the price, I can't complaint.

Two batteries for this price seems to me a great option. I have used them and I wouldn't know if there is any difference from the original. It also includes the charger, which is very useful to be able to recharge two batteries at once. Very happy with the purchase. Delivery was made on the indicated date and without any incident.

Works great. Charges quickly and also no issues with charging the original sony camera. No noticable difference in battery life between the original battery and these after a couple months of use.
Only downside is it's usb with no wall brick so have one handy for it.

They last almost as long as the original batteries at half the price, definitely a good purchase.

Sony batteries are way over-priced so I bought these based on good reviews. They work as well as originals at a fraction of the price. I had purchased a different generic battery awhile back that also worked, but every time I started up my Sony a7iii I would get a warning message about using a non Sony battery. These K&F Concept batteries do not cause that warning to pop up. I see no reason to buy Sony batteries and charger when these K&F Concept batteries and charger work as well at a fraction of the price.

Ok , batteries definitely don’t last as long as the OEM Sony batteries but throw 2 in a battery grip and it’s not even an issue during most shoots.
