Customer Reviews
Customer Review: This really is an awesome trimmer. Used it for the last 2 1/2 months of the grass-growing season and its has performed flawlessly.. The battery holds a surprisingly lengthy charge. The string seems sturdy, not always breaking at the first “hit” of an obstacle. Its not a heavy trimmer, its easy to maneuver and maintain. Comes with a second battery and 8 extra string spools – everything needed to keep it humming for many summers to come. Its a less-known brand, but for the money, I’m so glad I purchased this one.
Customer Review: At first I’m not really sure about switching from my gas weed eater to electric ones. After trying to start my gas weed eater 15-20 minutes every time, I decided I’m going to try this new electric weed eater/trimmer. Today I used it for the first time and let me tell you, it was one of the best decisions I’ve made. Very easy to assemble, very light weight and very easy to use. Push two buttons and it starts every time. Very powerful and the battery lasted long enough for what I have to do. It comes with 2 batteries so that’s even better. If you are thinking about switching to electric weed eater, this is the one to get. Plus, the price is not bad at all.

Customer Reviews
Customer Review: I like it. It’s light. Very maneuverable. No Gasoline. No hard starting problems. No oil. No battery to have to recharge and store in my garage to burn my house down. There is no issue with the cord. I have outlets and I have great extension cords (purchased on Amazon). There are a few videos on YouTube that give hints and methods on how todeal with the cord (e.g. work in the direction away from the outlet) that if you follow them you will forget you are even using a cord.
Customer Review: After two short years of using the Black & Decker cordless weedeater, the battery died would no longer hold a charge. It was out of warranty and there was a lot of information on the Internet about how bad these batteries were. I chose not to replace it. Having a long extension cord from my older weed eating days I decided to buy what I thought was a cheap plug-in model to do my once a year weeding. There is nothing cheap about this weedeater it works great! So much lighter then the battery model and easier to use with the exception of dealing with the cord but I found that very easy to get used to. It is very light and easy to use also it is very powerful. The biggest and best surprise was that the automatic string feeder in the head flawlessly. I don’t know how it works but it automatically feeds the line out as it senses or line. Awesome!PROs:Inexpensive (One quarter of the price of a cordless model)lightweight and easy to use. (Compared to the very heavy battery operated model)Automatic string feeder works flawlessly.Powerful.Endless power, no battery that needs rechargingCONs:Power cord

Customer Reviews
Customer Review: I use this to cut the grass on my small lawns and trim the edges 7 such. For this it works absolutely wonderfully. On the other side of my back fence is a forest and keeping the tall grass & blackberries at bay takes a bit more time as this is a single string unit that uses slightly lighter string than the big gas powered ones; that said, I have found that if I take a little more time cutting the jungle, it does an excellent job there as well.The batteries (standard size) last a decent amount of time – adequate to finish my two small lawns (10’x15′ & 15’x20′) and the trimming around them on two batteries. Dealing with the jungle takes a full battery+.Changing the string cartridges is very easy, and when the string gets stuck from heat and won’t advance (a very common occurance on all string trimmers), it’s very easy to get it un-stuck.
Customer Review: Why did I wait to switch to a Ryobi weed wacker. Its so easy to use, just connect the battery and your good to go. It surprised me how powerful it is. The battery last like 40 min which is more than enough time. Its very light weight so I dont feel tired once I finish. It less expensive than the traditional gas powered and you no longer have to buy gas or change the oil.

It includes auto-feed, a foldable shaft for compact storage, and a 12-inch cutting diameter. The kit comes with a screwdriver tool and an extra spool, which is thoughtful. While not a name-brand tool, it holds its own for light to medium-duty work and offers excellent value for Milwaukee battery users.

Customer Review: The little weed eater that could! I was skeptical at first, but after setting it up and using it on my 1/4 acre property, it handled all the weeds and high edges\\bushes well. It knocked out all the edging and can rotate with the wheel to make it much simpler and quicker. It is a decent size and very light which help with a big backyard as to help not tire out too quickly. I have only used a couple times but would highly recommend. Works with Milwaukee battery and still had more than enough battery to finish the front and backyard.
Customer Review: This is a great trimmer, it is very sturdy and quiet when running. Light weight and the fact you can run it on M18s makes it where your not fighting with a cord or mixing and storing gas. It has an auto feed function for the line so your not having to cut and feed your line every time you tap something like a fence which is personally my least favorite part of weed whacking. Definitely worth the purchase.

This 40V cordless string trimmer packs a punch with adjustable speed control and an auto-feed head. The cutting width adjusts from 11 to 13 inches, letting you balance runtime and coverage.

Complete Buying Guide for String Trimmer
Essential Factors We Consider
Choosing the right string trimmer depends on your yard size, terrain, and personal preferences. First, decide on the power source: corded electric models are lightweight and offer unlimited runtime but tether you to an outlet. Cordless battery trimmers provide freedom and are quieter, but runtime depends on battery capacity—look for at least 2.0Ah for small yards, 4.0Ah+ for larger areas. Gas-powered trimmers are the most powerful for overgrown lots but require mixing oil, pulling cords, and regular maintenance. Cutting width matters too: 10-12 inches for small gardens, 14-16 inches for bigger spaces. Shaft type—straight shafts reach under obstacles better, while curved shafts are more ergonomic for open areas. Line feed systems: auto-feed is convenient; bump feed gives more control but requires manual tapping. Weight and balance affect fatigue; test if possible. Finally, consider attachments or 2-in-1 edging functions to maximize utility.
Budget Planning
String trimmer prices vary widely. Budget models ($50-$100) are often corded or basic 18V battery tools—good for small, simple yards. Mid-range ($100-$200) offers better battery systems (20V-40V), auto-feed, and sometimes 2-in-1 edging. High-end ($200+) includes professional gas models or premium battery platforms like EGO with advanced features like POWERLOAD. Factor in ongoing costs: batteries ($80-$200), replacement line ($10-$20 per spool), and for gas, oil and spark plugs. A corded model has the lowest long-term cost, while battery ecosystems can be expanded with other tools. Set a budget based on how often you’ll use it and the severity of your trimming needs.
Final Thoughts
A string trimmer is a long-term investment in your lawn’s appearance. Don’t just buy the cheapest or most powerful—match the tool to your specific tasks. For most suburban homeowners, a cordless 20V-40V trimmer with auto-feed and edging capability hits the sweet spot of power, convenience, and value. If you have a small yard and nearby outlets, a corded model like the BLACK+DECKER BESTA510 is unbeatable for simplicity and unlimited runtime. Gas trimmers remain best for professionals or those with acreage, but the gap is closing with high-voltage battery tech. Read reviews, consider battery compatibility if you own other cordless tools, and prioritize ease of use—you’ll thank yourself every time you tackle overgrown edges without a struggle.
Frequently Asked Questions
Q: Should I choose a corded, cordless, or gas string trimmer?
A: Corded trimmers are lightweight, powerful, and cheap to run but limited by cord length (typically 100-150 ft). They’re best for small yards with nearby outlets. Cordless (battery) models offer mobility and quiet operation; choose higher voltage (20V-40V) for more power and longer runtime. Gas trimmers deliver maximum power for large, overgrown areas but require fuel, oil, and more maintenance. For most residential use, a quality cordless model is the best balance.
Q: How do I choose the right cutting width?
A: Cutting width determines how much ground you cover per pass. For small gardens or tight spaces, 10-12 inches is sufficient. Medium lawns benefit from 13-15 inches. Large, open areas or dense weeds call for 16 inches or more. Wider widths reduce mowing time but may increase weight and battery drain. Consider your typical vegetation: thick weeds need more power, so a slightly narrower path might be more effective than a wide, underpowered cut.
Q: What’s the difference between auto-feed and bump-feed?
A: Auto-feed systems automatically advance the line as it wears, usually by sensing tension or on a timer. They’re convenient and reduce downtime. Bump-feed requires you to tap the head on the ground to release more line; it gives you control over line length but can be tedious. Auto-feed is great for beginners and long sessions; bump-feed is preferred by some pros for precise line control. Both work well if maintained properly.
Q: How often should I replace the trimmer line?
A: Replace the line when it becomes too short to cut effectively (usually when it’s less than 2-3 inches) or if it’s frayed and breaking frequently. With auto-feed, the spool lasts longer but still needs swapping every few months with regular use. Keep extra spools handy. For optimal performance, use the line type and diameter recommended by the manufacturer—thicker line handles tougher weeds but strains smaller motors.
Q: Can I use a string trimmer for edging?
A: Yes, many modern trimmers are 2-in-1 or have edging capabilities. Look for a model with a pivoting head, wheeled guide, or dedicated edging attachment. For best results, use the trimmer at a 90-degree angle to the edge and walk slowly. Some users prefer a separate powered edger for heavy-duty borders, but a trimmer with edging function is sufficient for most home lawns.
After testing and reviewing dozens of models, we’re confident that the BLACK+DECKER BESTA510 is the best overall string trimmer for most homeowners—it’s powerful, reliable, and affordable.
