Key Features of the electric trimmer
- 2-in-1 Functionality: Quickly converts from a string trimmer to a wheeled lawn edger using a dedicated edge guide.
- Automatic Feed Spool: This model eliminates bumping and interruptions thanks to its auto feed spool, streamlining yard maintenance.
- Powerdrive Transmission: Featuring a robust 6.5-amp motor, it’s engineered for trimming thick weeds and overgrowth without bogging down.

These features, along with the 14 inch cut path, make it an effective lightweight lawn tool for trimming around borders and hard-to-reach corners.
Real-World Performance Testing
When putting the electric trimmer to the test, it stands out for tackling regular grass and lawn edges with satisfying consistency. The 14-inch cut path and auto feed spool make quick work of open spaces, while the wheeled edge guide provides crisp lines along walkways and garden beds.
Power comes from its 6.5 amp motor—comparable to other corded weed eaters in its class—which operates smoothly and without the downsides of battery recharge downtime. According to LawnStarter’s expert roundup, this model is best suited for light-to-moderate trimming.
Limitations include the rapid consumption of trimmer line via its automatic feed system, meaning users may need to refill line more frequently. Also, its corded design restricts range compared to battery-powered options.

How It Compares to Alternatives
In terms of price, this BLACK+DECKER trimmer competes well at around $50, especially given its 2-in-1 capabilities. While it offers more versatility than basic single-purpose garden equipment, users comparing it to the BESTA510 at Home Depot or models like the Greenworks 5.5-Amp Corded Edger will find that price and feature set are highly competitive.
Competitors such as the Worx WG163 offer cordless operation, while the Greenworks 21212 provides a slightly smaller cutting width but similar corded convenience. The BLACK+DECKER model’s 2-year warranty is another plus for budget-conscious buyers.
Who Should Buy This Product?
This tool is ideal for homeowners with small to medium-sized yards who want a low-maintenance, affordable solution. It’s perfect for those who don’t want to deal with gas engines or battery charging and value the consistent performance of a corded weed eater.
Elderly users and beginners will appreciate the lightweight feel and simple operation. However, landscapers or those with oversized lawns may need a more heavy-duty machine with greater mobility or run-time.
