Works really well. Cit through my Saint Augustine grass like a breeze and it is super thick. Very happy with purchase. Battery has good life, charged it for a full 24hrs before use and it last a long time. They send 2 blades and the battery with charger which is a huge plus because everything else I looked at you had to purchase those separately and it was just as much as the edger. This is a great deal and worth the money. Highly recommend 👌

Great thing to have.

Size: 9 inches

Great thing to have. For my small yard, it is perfect for me. Yes, the battery life does not last as long as I would like be, but I would buy this again. Great power and speed.

Edging made easy

Size: 9 inches

Surprised how well this works. I was looking for no cord for long driveway. The battery takes a bit to fully charge, but lasts for the entire job. The levels for depth make edging around d flower beds or raised beds easy- not really a trench, but gives a good edge. Lightweight and easy to manage. Definitely lighter than my corded edger. The blade is sensitive and the guide to keep it steady along concrete is not great- just need to make sure you watch closely or it will spark when it hits the concrete.

Works well, a little under powered

Size: 9 inches

Works well, a little under powered when I used it for the first time. Once you get the groove established it works great to maintain it

It’s junk

Size: 9 inches

Deserves a zero. Like some others said on here, it runs for 3 seconds and just stops with battery fully charged. I got it for Christmas so too late to return. More China junk.
