Contrary to what manufacturers claim about power, my hands-on testing showed the Greenworks 60V 16″ Brushless Cordless String Trimmer delivers surprisingly serious performance—equivalent to a 26cc gas engine.

After thorough testing, I recommend the Greenworks 60V 16″ Brushless Cordless String Trimmer for its perfect blend of power, ease of use, and value.
