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.

Very light and effective trimmer

Style: 20V String Trimmer Kit

I’m very well designed trimmer that cuts through grass and weeds very easily. The battery lasts about 45 minutes. It’s fairly light and easy to use. I think it’s also a pretty good value.

Perfect trimmer for my yard.

Style: 20V String Trimmer Kit

Works great. Love all the features for the price. I can get two yard trims out of 1 battery charge which is fine for me.
