Great alternative to the Sony branded batteries. These things are so small and lose power pretty fast so it was necessary to get more. Really enjoy having a bunch of these charged up and ready during a wedding! 5

Works well after more than 50 charges. Saved some money. I was so impressed with the Watson NP-FW50 Charger on Sony batteries I decided to try the battery. 5

The battery life on my camera isn't great, so extra batteries are always necessary! 5

Gladys GD	01/08/2024
I bought 3 of these and I can say that they last longer than the original Sony battery and for the price they're totally worth it! 5

Nipper from CANADA THE GREAT WHT NORTH	15/06/2024
Its great to not have to worry about running out of power / even better 4 batteries for the same price as a name brand . ( Canadian pesos are not equivalent to U$ ).Charges very fast ( 2 leds instead of 3 light on sony charger ) I had a second manufacturer battery for my canon , been on the lookout for one for my medium format SONY A7R /it eats batteries . I 've been crying since the seventies / eighties at B+H adds in the back of photo mags . My canon AE1 or Minolta 35 mm 's batteries lasted 3 yrs /not like what you young pups have to deal with . My Kodak brownie or pocket 110 don't need batteries (1968-77)!!!!!!!!!!!!!! 5

Purchased 4 of these batteries for backups when shooting weddings. So far they work every bit as good as the Sony batteries, but at half the price. 5

Kelsey	08/06/2024
This battery works well, and is nice to have as a spare. The Sony a6300 burns through batteries fast so it is great to have a spare 5

Initial useage appears to show similar performance to higher priced ones. Time will show if any long term differences occur. Pleased at this time 5
