WORX WG168 40-volt Lithium Cordless Grass Trimmer and Edger
If you want to go head-to-head with the top rated Black and Decker, then you’ve got to go with this WORX WG168 40-volt Lithium Cordless Grass Trimmer and Edger. Weighing nearly eight pounds, it features about the same run times, 30 minutes in low power and about 15 minutes in high power. The main difference is that you only have three speeds to choose from instead of five; a bit less versatility overall. The trimmer head pivots to make it an edger, and the handle adjusts to fit your trimming needs. While it also comes with a three year warranty, its slight lack of versatility and heavier weight keeps it from being the top dog.
