Initially defective poor quality
This item was initially defective and I needed one so I ordered another thinking it was a fluke. Both devices would not turn on. The second one briefly turned on for about 30 seconds and died. The major inconveniences that I can't return it in the normal way. I have to bring it to UPS and there isn't one near my house. I am very disappointed with this item and also with the return policy

Came in skeptical, but it's GREAT!
I read all the bad reviews I could on this thing and considered it an acceptable risk considering the price. Assembly was easy and the instructions were fair. Not amazing, but once you handle the edger, the gist is clear. I was skeptical overall that the horsepower and plastic guard weren't going to be enough. I ran it for nearly 45min stopping every 5 or so to check the blade and guard. It stayed tight and I was able to manually turn the blade to make sure it was working right. My front yard and sidewalk have been neglected for a few years. I would sometimes edge it out with the weed Wacker, but couldn't get it as clean as I wanted without breaking a LOT of line. When I was done, I noticed the guard had a lot of soil and grass buildup that I was able to take out easily with my fingers. There were a few times I scraped the sidewalk edge, but the blade is still solid and ready for more! I was surprised at the quality and as you're going over an area, it feels solid and not squirly or out of control. My uses are going to be mostly suburban maintenance on my own yard. If I had more land or something bigger, I would consider something larger. For my yard and purposes, this edger is going to work just fine! Did not notice any issues with the blade getting loose, but stayed aware of it. There is a lock nut that keeps it in place. I imagine over time and switching blades, this is going to lose its locking function, but I already see amazon has replacement blades that come with new lock nuts!

Works great, easy assembly and no issues!
Using the weedeater for edging was too hard, so I purchased this. It works great! It was easy to assemble and easy to use. My lines are perfect, but the size, durability, and power of this gem get the job done, and it's lightweight enough that I can easily maneuver it around the yard. I chose a corded one so I don't have to deal with battery life or charging.

Easy to handle
Style: Lawn Edger w/(1) 4.0 Ah Battery
This is fantastic. It was a breeze to put together, the battery lasts a good 45 minutes or more, it is easy to handle, and does a terrific job of edging the concrete driveway. the roadside curb, and the borders of my flower beds. It is not too heavy and has loads of power. I am a 5'1" woman 81 years old and this tool is very easy for me to use and carry. The size is not too long even for me to maneuver. It is easy to lean if you get clumps of dirt in the housing for the blade and it is adjustable to suit the depth needed at the time. It seems very well made. The price was reasonable and I think we may be friends for quite a whole.
