I'm a casual shooter, so these definitely go the mile when I'm out and about taking pictures. I think these, along with the Sony battery that comes with the camera, can last me 2-3 days without charging. I do think it would've been better for me to just order the charger and not the two batteries that came with it, and just one Sony battery to have just two batteries to worry about. This highly depends on how you do things, so might not be it for everyone.I also don't think these batteries last as long as the original Sony batteries - going along with reviews with third-party batteries, but this entire setup can be had for half the price of Sony's original battery, so this is a good deal.

Bought for my Sony A7ii and it works brilliantly

Works really well. Well constructed.I purchased it to have extra batteries for my a6700 so useful to have a couple of spares.What was useful and convenient is that the two batteries that came with it were pretty well charged up at charging didn't take long. Unlike the battery that came with the camera which was totally uncharged and took many hours to charge fully.Very happy with this delivery.

Lets cut to the chase.I bought these for £38 on an offer which is superb value for money.They last around 70% of an official sony battery for photos and videos.For videos, If you record long form (Wedding ceremonies etc) they off brand batteries get hot quickly. They also dont give you clear indications of when they are running low, anything under 30% on the battery life and they will need changing for video as the battery gives zero warnings and with just turn the camera off or freeze it up. For photos that means you lose 1 picture. for video you could lose the whole file. So make sure not to use them in direct sunlight or anywhere very warm and always change the battery for important longform content.For me they work perfect as I mostly shoot photo and hybrid short clip video and I have bought more since the first purchase.

Does the job. Good charger, good batteries - last just as long as Sony ones.

Update: had an issue with first item sent out but seller reached out and helped sort the problem. Great communication, extremely professional and determined to set right. Product themselves, I'm now very impressed. Works great holds charge for a few days with very little drain. Yes they don't last as long when being used as the official Sony ones but they are three times the price. Two batteries will last you plenty but if you require a days worth then just just order another set then you'll have four to last you the whole day. For a Sony equivalent you'd need at least three costing around £70 each give or take so I'm quids in and have faith that if I encounter a problem these guys with fix quick shape.

I've used Energon batteries before and they are very good value for money, especially with the charger which can use USB-C or Mini USB to charge.

Good battery duration, compatible with A7 IV although camera gives a warning upon turning it on. I had purchased a similar kit from two other suppliers, batteries could not even lock in place.
