Best praise vs top criticism for Kobalt 80V Max 21-Inch
“Go with 80V. Max voltage is the most important spec for electric mowers and that's what will keep it from bogging down. I have an 80V kobalt that uses the same batteries as some other tools so I always have one battery charged up and ready to go.”
