The BLACK+DECKER GH900 is a lightweight, corded electric 2-in-1 string trimmer and edger featuring a 6.5 Amp motor and a 14-inch cutting path. It excels in performance with high-torque transmission and Smart Edge capabilities, making it effective for residential maintenance up to 1/2 acre. The main trade-off is the restriction of mobility due to the power cord and potential line wear on concrete. It is best suited for homeowners with small-to-medium yards near power outlets.

The BLACK+DECKER BESTE620 is a corded electric 2-in-1 string trimmer and edger featuring a 14-inch cutting path and Automatic Feed Spool technology. Its primary advantage is unlimited runtime powered by a 6.5 Amp motor, making it ideal for consistent residential use. However, the tethered cord limits mobility and requires careful management near power sources. It is best suited for homeowners with small to medium yards located near electrical outlets.

The BLACK+DECKER LST201 is a lightweight, cordless string trimmer and edger designed for small to medium residential yards. Its key strength lies in the POWERDRIVE transmission and automatic line feed system, which simplify trimming tough weeds. However, the short runtime with the included battery and potential motor strain on heavy growth are notable limitations. It is best suited for homeowners needing a budget-friendly, easy-to-use tool for weekly maintenance.
The BLACK+DECKER BEST935 is a lightweight, corded electric string trimmer designed for basic household yard maintenance. It offers unlimited runtime and automatic line feeding, making it easy to use for quick touch-ups. However, the corded design limits mobility, and the 13-inch cutting width is insufficient for heavy-duty or large-area jobs.
