Easy to use for a clean looking cut!
I do wish there was a cordless version but I'm so glad I bought this. It took some time to edge everything the first time because I had to cut the lines but it's been a breeze ever since. I just walk the perimeter of the yard and driveway and it does it's job with ease.
The front wheel has three settings which determines how far down the blade cuts and the blade has two settings for edging or trenching. The handle is stationary but it can be lifted up or down. There's a guideline on top of the blade guard that helps identify where the blade is going to make the cut. TIP: Lean it back on the back wheels before pulling the trigger and slowly bring it down because it will jump if the blade isn't lined up and touches the concrete.
It doesn't roll well in the grass but it's very smooth when rolled on the concrete. It's definitely worth having to give a clean and finished look. It's well built and isn't too heavy but definitely has some weight to it. It's only loud when the blade hits the concrete otherwise it sounds like a drone. The only complaint I have is that I have to watch the cord closely other than that it's the perfect tool to give a clean look to the yard.

Great product for the $$$$
This edger is awesome. Easy to put together. Intuitive. I put it together inside of 10 minutes. Shifted the edger "guide" down, and went to work. This corded electric model is WAYYY cheaper than the battery powered (or gas powered) models, and is absolutely up to the task. Lightweight and maneuverable. Quiet. Easy to store. The motor got a little "bound" when I tried to edge too fast, but the manual had clearly warned me on this - to back up, let the blade get back up to speed, and then edge again. The lawn edges are now straight, well-defined, and immaculate.

Great but could be Epic
If you’re looking for a solid edger for sidewalks and driveways, this is a great tool. It’s powerful, well-built, easy to assemble, and simple to use. For edging, I would definitely recommend it.
However, I wouldn’t recommend it as a true trencher. I bought it for both purposes but mainly needed it for trenching. The maximum cutting depth is only about 1.5 inches, which isn’t deep enough for most garden borders or running cable. In my opinion, a real trencher should be able to reach at least 3 inches deep.
The limitation comes down to the blade size and guard design. WORX could improve this model with a larger blade guard and additional wheel depth settings. If they released a version capable of 3–3.25 inch trenching depth, it would really stand out in the market.
Overall, it’s an excellent edger, just not a true trencher.

Works Great!
Much quieter than I was expecting. Lawn had needed this for years, I regained 6"-10" of driveway/sidewalk back. Makes the rest of the neighborhood look bad LOL Only the cleaning up wore me out, but it should be much easier next time.
