5 of 5 Great experience! January 20, 2024
Reviewer: Christopher A from Apopka, FL United States  
I bought 4 batteries for the AIO mini strobes. It was very easy not only to find the right batteries, but the website told me that a newer version was being sold. The UMS4 charger I bought for them is amazing!
