## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by S***R on January 2, 2026*

Must charge two batteries at one in order to wish

### ⭐⭐⭐⭐⭐ Very functional
*by M***H on August 1, 2025*

Works great , my only gripe is it does not take type C chargers.

### ⭐ Didn't last 18 months :(
*by M***S on January 13, 2026*

Good price, but one of the two batteries failed after 18 months and less than 25 charging cycles. I see now from other reviews to not use these in a flashlight. Disappointing to learn this after the fact and scared to use the second remaining battery just in case its hazardous. Advice is to look for something else if you ever want to use these in a flashlight. Fast charge. Failed too quickly.
