I've used K&F brand gear before, I always thought it was good enough for non-professional work and this battery/charger kit fits right in with that sentiment. It takes about 75-90 mins to charge to full, the batteries don't get hot while charging, and I estimate they have about 85% life of an OEM Sony battery at less than half the cost. All in all, it's a fantastic deal and I'm glad I found this kit. I'll update this review if I find any longevity or heat issues down the line.

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.

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!

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.

Got these to use with my Sony a7 and they held up great for an 8 hour wedding day doing video!

So far these batteries and charger are working properly and keeping my Sony A7 III powered up. I haven't noticed an issue with battery life yet, but its only be a few weeks.

One of the problems of being a photographer is the cost associated with most gear. I already sink tons of money into lenses and bodies, so I really would like to get a break on the other stuff where I can. I opted to get these batteries instead of the Sony version because the price was MUCH lower. They came charged to about 60-70%, and I popped them in the charger to get them to 100%. As normal, my A7R5 pops up a warning that 'this isn't a recognized battery', but they work great anyway. The A7R5 is a battery hog as it is, so I needed to have at least 4 extra batteries for Weddings and long sessions. These work great, and for the price, I can get more sets and have 8-10 spare batteries with me on any shoot. Doesn't seem to make sense to me to buy the official name brand batteries. One thing I did note, when you plug an official Sony battery into this charger, the charger indicator doesn't function. But if you leave it in there for a while, I do overnight, it's always 100% the next day. So, value for money, these are great.
