I was sceptical at first, but in a last minute pinch before heading on a trip to Japan I purchased this battery set and was not disappointed. Throughout my trip they worked great, charged as expected and lasted about as long as my Sony battery as far as I could tell. Two weeks in Japan so two weeks of use not one problem or hiccup. Great value for the price.

This charger and batteries are great. They work well with my Sony camera, perfect size, great value, functions as a Sony battery does and great quality!

This is a great backup battery set for my ZV-E1. It’s much cheaper than buying Sony originals, and the dual charger makes it easy to charge two batteries at once.The charger is compact and easy to travel with, and so far the batteries hold a solid charge during shoots. Very handy to have in my camera bag.

So far so good! Efficient and cost effective!

Buying these batteries were a game changer for my shooting days. I go through 3 batteries easily, so the multiple charging dock is extremely helpful and functional for when I'm on the go at shoots.

I just went out to use the camera for on the trail. I had the other batteries ready just in case. I am still on that same battery. Though it went down pretty fast originally, it has held for at least three hours. If you looking for some good batteries for a good cost, would definitely recommend. They aren’t as long as the Sony batteries but you get your moneys worth. Charge speed is good and the Functionality is okay to me.
