Score: 76/100Rankings

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 unlimited runtime and powerful 6.5 Amp motor make it ideal for homeowners near power outlets. However, the cord restricts mobility and requires careful management to avoid disconnection.

The BLACK+DECKER LST201 is a lightweight, budget-friendly 20V MAX cordless string trimmer and edger with a 10-inch cutting swath. Its automatic feed spool and edger conversion make it easy to use for small yards. However, the limited battery capacity and single-speed operation restrict its performance on tougher jobs.
