Great!

works as intended batteries last quite a while

decent speed on the charge and the batteries fit my Sony a6400

A few years after purchase, these batteries don't seem to hold their charge very well and unless they've been charged up within a week of use. THe charger still works great, and the batteries are still working great as I stay on them pretty well, but I wouldn't say they are as reliable as Sony's legit batteries. I run a small creative media business, and reliability is a #1 priority in my mind, and overall this makes the cut for being a super cheap alternative and lasting as long as they have. They've made me a ton of money!

EXCELENTE CALIDAD

Good value for two batteries. I prefer wall chargers over USB, but wanted to have a dual charger like this, too. If you look at the pictures of similar chargers, you can see the charging slots of many are the same and interchangeable. Some major camera stores even sell those separately for a few dollars. I have lots of single wall chargers that look the same way and can swap the charger plates, making this a two-camera charger for whatever two cameras I travel with.

Fast charging ! great to have dual charger , extra batteries especially when going out !

After 3-4 months of having these batteries and using very little, they no longer charge at all and my camera reads "battery exhausted" anytime I put them in.
