Finished the job without stopping! Having a second battery on hand completely changed my yard maintenance routine.

Stephan V.

The 4-bar fuel gauge is so convenient. I always know if I have enough juice before heading to the far end of the property.

Robert D.
Verified Customer

Slides on with a solid click. Genuine 5.0Ah cell gives noticeably longer runtime than generic batteries I tried before.

Thomas B.
Verified Customer

Worth it just for the convenience. By the time I drain one battery, the first one is already fully recharged on the dock.

Alfonso S.
Verified Customer

Great power consistency from start to finish. No loss of blower CFM until the final bar.
