The blade spins too slowly even at faster setting to do an adequate job even a maintained edge.

It was supposed to have a carbon fiber shaft, but was aluminum

Works as advertised. I also used the Ego string trimmer to mop up whatever the edger cut. Using the two together made the job super easy. It was easy to control, so I didn't tear up anything accidentally.

Works a hell of a lot better than my plug in black and decker edger. I just don't like that it cost nearly as much as the full product when this is just the attachment.

It really works nice; did my sidewalk edge smoothly and evenly. However, I am 6'2 and the best position for use causes me to stoop considerably which just causes back pain. No matter where I adjust the handle or the edge roller, still am stooped while in use. Like I said, it works very nicely, just be prepared to stop and stretch out your back if you are tall.
