Worx 20V PowerShare String Trimmer vs BLACK+DECKER LST522 20V String Trimmer

The Worx GT Revolution is the more versatile tool: it converts to a wheeled edger and a mini-mower without tools, has a telescoping shaft and rotating head for tall or short users, and ships with two batteries. The BLACK+DECKER LST522 is lighter and simpler, with a two-speed switch and a bigger single battery, but it only trims and edges. Owners rate the Worx higher overall. Buy the Worx if you want one tool for trimming, edging and light mowing; buy the BLACK+DECKER if you want a light, basic trimmer that edges.

• Choose the Worx GT Revolution if you want a trimmer that also edges on wheels and mows light grass, with two batteries and a shaft that adjusts to your height.
• Choose the BLACK+DECKER LST522 if you want a light, straightforward trimmer with a two-speed switch and a larger single battery.
