BLACK+DECKER BESTA510 Weed Wacker with Auto Feed (14-Inch 2-in-1 String Trimmer / Lawn Edger)
Product description
The essentials first
If you want a weed wacker that’s mostly about getting the job done (not babysitting it), the BLACK+DECKER BESTA510 is built around two things: auto line feeding and a simple switch from string trimmer to wheeled edger. On paper, that combo targets the most common annoyances with electric trimmers—having to keep bumping the spool for more line, and stopping to retool when you want cleaner edges.
This is an electric 2-in-1 weed eater / lawn edger meant for routine yard cleanup: trimming grass and weeds in spots mowers miss, like around fences, along garden edges, and in hard-to-reach areas.
Key features that matter day to day
The standout here is the Automatic feed spool technology. Instead of relying on bumping the line to advance it, the trimmer is designed to feed line automatically, which can mean fewer interruptions while you’re working. That matters if your lawn has a lot of edging or if you’ve already gotten tired of the “bump, pause, bump again” rhythm.
It also uses a 6.5-amp motor with POWERDRIVE transmission, positioned for stronger performance when trimming tougher weeds, grass, and overgrowth. Electric yard tools can feel a bit limited depending on conditions, so if your yard typically needs more than light touch-ups, this spec is at least aimed in the right direction.
For edging, you don’t need a separate tool. The wheeled edge guide lets you rotate to convert from trimmer to wheeled edger. That wheeled setup is the kind of detail that can make edges look more consistent without you trying to hold a perfect line by hand.
What you’ll notice in use
A lightweight design is the other practical win. With an adjustable handle and height positions, you can dial in comfort and control for your stance. That’s useful for longer sessions—especially when you’re edging multiple sections where posture matters.
There’s also a cord retention system intended to prevent accidental cord disconnection. With electric string trimmers, this is one of those things you don’t think about until it saves you from a frustrating “pause” mid-job.
And the 14-inch cut path is meant to help you move through areas efficiently while trimming.
Quick micro-experience: imagine doing a loop around a driveway edge. You start as a string trimmer to clear weeds in tight spots near landscaping, then rotate the unit to use the wheeled edger guide along the straight sections. The idea is that you keep working the same task—just in a more controlled edging mode.
Where it shines (and where it may fall short)
Worth considering if you want a straightforward electric string trimmer that also handles edging, without making you stop to manage the line constantly. The auto feed approach is especially appealing if you dislike interrupting your flow.
It’s also a sensible pick if you primarily need cleanup in mower-missed areas and you care about getting edges that look deliberate.
That said, keep expectations realistic. This is a corded electric tool, so your range is naturally limited by your extension cord setup (the data you have doesn’t cover battery or cordless use). If you regularly deal with huge, remote areas far from outlets, that limitation could matter more than you expect. Also, while the 2-in-1 conversion helps, you’ll still be doing an “edging pass” manually—this isn’t replacing a full landscaping overhaul or a dedicated pro-grade edger.
Who it’s for (and who should skip it)
It makes sense if: - You want one tool for trimming and edging with a rotate-to-convert approach. - You’ve had to deal with manual line feeding or bumping and want fewer interruptions. - Your yard has weeds and overgrowth that benefit from a 6.5-amp motor and POWERDRIVE transmission. - You want a lightweight design with adjustable height for better control.
You may want to skip it if: - You need a fully cordless experience. - Your property is so large or so outlet-limited that cord management would slow you down. - You’re after features not mentioned in the provided details (for example, specific attachments, advanced guard systems, or storage specifics).

Final verdict: the BLACK+DECKER BESTA510 is a solid “practical yard maintenance” choice if auto line feeding and a wheel-guided edging mode are what you care about most.
