### ⭐⭐⭐⭐⭐ Good
*by A***R on June 26, 2025*

Arrived on time. Works great.

### ⭐⭐⭐⭐⭐ Long lasting, highly recommend
*by D***O on August 8, 2024*

I bought this battery with a leaf blower. I used the leaf blower on and off all day (mostly on the highest power setting) and the battery lasted without an additional charge.At first I was surprised it didn't have a slide in charger, only a plug but I personally like that better. Although you can only charge one battery at a time, you only have to store a plug... great design.
