### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    This is GREAT!
  

*by B***N on Reviewed in the United States on December 14, 2022*

I had a blade trimmer whose battery suddenly stopped working. I bought this one on a humble... but it worked! I am so pleased. It was so reasonable.

### ⭐ 1.0 out of 5 stars







  
  
    Chargers fail quickly
  

*by B***N on Reviewed in the United States on December 22, 2023*

I have found that 21v chargers for hand chainsaws are all rotten, whatever the brand name.  This particular item failed after just topping-off one of the two new batteries that it came with.  I have now accumulated 8 batteries but have no working 21v chargers.  A 20v DEKO charger, that came with a hand drill, has charged drill batteries and chain saw batteries by the dozen for the past two years.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Both battery and chain are working perfectly.
  

*by S***L on Reviewed in the United States on July 20, 2022*

The battery and chain are used by the chainsaw and they are working perfectly.
