I have a Sony A6000 and it fits perfectly. The battery format is the same for the entire Sony Alpha line, even on those with a full-frame sensor; it's good to know if I want to upgrade my hardware one day and replace my case with a better one.
The charger and the two batteries correspond to the description. I've seen comments that said these batteries didn't hold a charge or weren't as good in quality as the official ones. For my part, I did not notice any difference and I emptied these batteries and the one that comes with the box several times. This is very reassuring and it feels good when you see the price difference between these and the price of the batteries produced by Sony (between 65 and 80€ each depending on the site)! )
A little extra: the charger for these batteries is so practical that I don't even carry the charger that came with the Sony A6000 anymore. I just have this one with me in the bag since it is much more practical and compact than the “official Sony”.
Anyway, it's a great buy.

Amazing value, but battery last about 10% less then oryginal. Having said that it is fraction of the cost plus you get quick charger.

I've been using these batteries (for my a6000) and charger for nearly a year now and haven't been disappointed. Sure the batteries don't last as long as the original Sony ones but that was expected and they are much cheaper. Charger works well and is handy and still use the spare batteries all the time. If you're looking for some cheap spares then these are a good shout!

I tested 5 under battery brands to replace the original battery for my a6400 (video available on YT).
This battery being 3-4 times cheaper than a Sony, offers a very light better battery life (sony 1h25 in 4K approximately, K&F Concept 1h32) and in addition offers you almost non-existent discharge against the Sony that loses a lot of storage (sony in storage a few months, remains 30% battery, K&F Concept 99%, and it is confirmed in time of recording in 4k, amazing..).
Until then, she beats flat with stitching the Sony...
... BUT (it needed one)...
... she has a small flaw that does not (as much) the Sony. The calculation of the% remaining on the K&F Concept is far from predicted, when the battery indicates 0% it actually remains more than 25min of recording, so you have to get used to keep recording but at 0% and evaluate about 20 min before changing the battery.
Apart from in certain specific cases, it is very uncomfortable but a shame...
(This is the same for the Sony at 0% there are still several minutes of recording.. 10 minutes of head but there is less to spoil if we change to 0%)
In the end excellent battery I use without problems for several months, I strongly advise this battery even faced with the shamefully expensive Sony and that does not hold the charge on time!
Even if I choose, I prefer to get used to calculating that I have 20 good minutes left at 0% (the K&F Concept), than to take out my device after a few months to realize that I have only 10% left (the Sony). (especially 4 times cheaper)

Small, lightweight, fast and takes a standard Micro USB connector? What's not to like.
The batteries themselves seem very good. They’re a slightly higher capacity that the original Sony ones at 1100mah. Having tested them, they last roughly the same length of time as the original Sony ones which is great.
The charger is small, light, takes two batteries (which charge simultaneously) and takes a standard Micro USB charger (which I’m sure you already have a small collection of). There are two LED lights that indicate when charging and when complete etc. The batteries are easy to load and are actually quite secure when in position.
Overall for the money it’s great and I’m happy to recommend it to any Sony shooter.

The only good thing is the charger. They batteries last for 30 min to an hour maximum.

I have several K&F Concept photographic accessories that, with a few isolated exceptions, stands out for offering very good quality products, at generally very low prices.
This is also the case with the set covered by this review, which consists of two batteries and the relative charger.
The two cells declare a capacity of 1100 mAh each, i.e. essentially in line with those of the Sony originals. Actually, in concrete use with both Sony Alpha 7R II and Alpha 6100, the autonomy is very similar to that offered by the standard batteries.
I did not find any sudden power drops, but the behavior during the download is progressive, as is the case with those branded Sony.
Note that the cameras mentioned also show the percentage of battery with these K&F Concept compatible ones, which are therefore recognized as if they were original parts.
The build quality is more than good, without detectable defects.
I would say that these K&F Concept batteries are equivalent to the best compatible batteries, which as far as I'm concerned are the Patona branded batteries, which I have been using for years.
The charger has two separate channels, which is why you can also charge one cell independently of the other.
Each channel delivers 730 mA of current, which means that a fully low battery will be recharged in approximately 1 hour and 30 minutes.
The fact that it is possible to power the charger itself even with a power bank and in general with any USB outlet that provides at least 2.1 A.
This particular model of charger it is more cumbersome than the other K&F Concept brand equivalents dedicated to the same type of batteries. This is due to the fact that the batteries should be inserted in it lying and not strung from above, resulting in an increase in the total volume.
With regard to the price, for 32.99 Euro it is already an excellent purchase.
In my case, I was lucky enough to buy it as 'used as new' for only 15 Euros, including Prime shipping (although the product was sold by a third party seller). I was given a product that has only the words used, because in substance it is indistinguishable from the new factory (perhaps it could be a reconditioned product, perhaps through the mere replacement of a faulty battery).
Given the excellent performance of the batteries and the useful two-channel charger, this is a very satisfying purchase.
