I was looking for extra batteries for my Sony a6400 and watched a comparison showing 4 different battery brands competing in which K&F Concept was the winner for longevity, so I decided to purchase them. The proof is in the pudding is all I have to say, these batteries have been with me for over a year and still hold up great as they did when I first got them and they can easily be placed in the charging dock for easy transport. And for the price, you cannot beat these!

I was looking for batteries for my Sony 6000a and found this. It was reasonably priced so I bought it. Charger works great for my Sony battery. However the K&F Concept batteries it came with didn't even hold a charge. I contacted customer service and they got back to me saying they will be sending me new batteries. So I'll update this review to let you folks know if I got the new batteries and if they work.

It is compact, it has two batteries and it is cheaper than the Sony one, the durability is badly done because I have just started
