### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Seems okay
  

*by A***O on Reviewed in the United States on May 31, 2024*

I used one of these for the first time for string trimming and blowing. I compared it to a Milwaukee brand 12.0. This 9.0 off brand lasted just as long for the same job and had 2 bars left. That's about 40 minutes of string trimming and 5 minutes of blowing.So far so good. Hope it lasts and doesn't overheat like some Lithium Ions do. Even the Milwaukee's sometimes do and I have had bad luck with the 12.0 Milwaukee's lasting more than 3 years.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Ordered this twice and kept receiving 2x6ah batteries and charger . Review is for what I received
  

*by R***D on Reviewed in the United States on March 21, 2024*

Battery level indicator lights are very dim and barely visible during the day. Fit tightly like oem. They don't last as long as oem but they are comparable. They seem to take twice as long to charge vs oem, regardless of what charger I use. No overheating as of yet. They work well 👍

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
