Great easy to use

Perfect for a senior yard lady 7 lbs and lasts about five years with indoor storage and cool environment for battery storage. I've been there for about 10 years using batteries and love it. FYI if you have a lot of trimming and edging you may need up to 4 or more batteries. But I would at least buy another 2 batteries and they hold a charge while storing. Also don't drop your battery on concrete, because that can cause a battery to fail.

Plenty of power. Successfully replacing the line and having the auto-feed feature work has always been a challenge but purchasing pre-wound spools by the six pack has been a game changer, making this tool easy to use.

Great weed eater for my husband who is recovering from back surgery. He usually uses a gas weed eater because we have 3 acreas. Light and efficient!
