### ⭐⭐⭐⭐⭐ Great product
*by J***E on January 14, 2026*

Works perfectly. Like how the charger can adjust to different sizes

### ⭐⭐⭐⭐ Batteries are OK, Charger works but kind of flimsy.
*by F***H on November 23, 2025*

The Batteries are fine, they charge and last adequately. The Charger worked great for a year, then the tension spring on one side broke. I can still charge one at a time normally. I am able to use the broken spring slot if I wedge something behind it to keep pressure on the battery. Charger should be more durable.
