This lightweight leaf blower is amazing. It's three speeds are perfect for so many different tasks. I've been using a corded leaf blower for many many years. They have always been a hassle. Dragjging a cord around, getting it tangled up in things, etc.etc. I can now use this leaf blower with my left hand or my right hand because it is so light and easily maneuverable. I wish I had gotten one 10 years ago. It usually runs for about 20 minutes on one battery. I've always got the second one charged up... so, 40 minutes is about all I can do at one time anyway... being 76 years old.
