Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ’em) products and single out the most convincing. While we’ve written before about other yard must-haves like lawn mowers, garden hoses, and even lawn chairs, here we’ve rounded up the best-reviewed string trimmers (also known as weed whackers) on Amazon for taming errant growth. (Note that reviews have been edited for length and clarity.)

Best light-duty string trimmers

Black + Decker LST300 12-Inch Lithium Trimmer and Edger

“This thing kills weeds and grass like it has a grudge. I’m seriously impressed with it’s effectiveness. I bought this because I needed to replace my old cordless trimmer whose battery was going downhill. I had that one for possibly ten years; it served me well. This new one makes the other look bad. It’s incredibly powerful and cuts through things the other never did. I was able to do my entire yard on one charge with plenty of power to spare. The best part is, it’s way lighter than the old one.”

DeWalt DCST920P1 20V Lithium-Ion XR Brushless 13” String Trimmer

“This has been the single most awesome yard tool that I have ever purchased. The battery is amazing and it takes jobs with the same gusto as a gas-powered trimmer. I have a bad habit of letting areas of my yard get overgrown before doing any trimming, and this trimmer eats through like nothing. And I am talking some thick weeds, and I have been known to use it to trim back azaleas and other woody stemmed bushes. I show it no mercy and it hasn’t disappointed! It is very lightweight and I have no problem using it for extended periods of time.”

Worx WG163 GT 3.0 20V Cordless Grass Trimmer/Edger With Command Feed 12”

“I was hesitant to get another electric trimmer, as the one I owned previously had a short battery life and couldn’t knock down a baby, I was wrong to doubt this one though. It is strong enough to handle everyday trimming and then some. The battery life easily gets me around the house and done with most trimming on one battery. The only times I have needed the spare is when I let the lawn become a bit overgrown and I needed to spend some extra time doing what was needed. I particularly love the trimming wheels for making my sidewalk look neat and clean. I’ve even had a neighbor ask if I had gotten it done professionally after the first time I used it.”

Best medium-duty string trimmers

Black + Decker LST136W 40V MAX Lithium String Trimmer

“Forty volts is a lot of juice for an edger. It cuts through weeds and edges along my driveway and walkways without any hesitation. And the battery lasts quite a while. I leave it on the maximum setting 100 percent of the time, and I can trim around all the trees and natural areas in the yard, and then edge around the back patio, the driveway and the walkways, and still have over 50 percent battery when I’m done.”

Greenworks 12-Inch 40V Cordless String Trimmer

“This is a true weed whacker! It’s the bomb — it does not play around. It whacks everything in its path, be warned. I love it — cuts my work time in half compared to my Ryobi whose battery just quit on me. I think the double line makes a big difference, and the battery recharges in two hours. I’ve been using it about three weeks with no problem so far. It is long, as some have mentioned, but that means I can reach under bushes easily. This Greenworks product is A+ in my book.”

DeWalt DCST990H1 40V Max Lithium Ion XR String Trimmer

“First, it is WAY more powerful than I expected. Using it on the low setting was plenty for me. I have a fairly big piece of property and do all my own landscaping. I have to weed whack around both sides of a long fence, sidewalks, garden beds, etc. When I was done, approximately 40 minutes later, I checked the battery-life indicator, and it showed I only used about one-third of the capacity, so this battery will go quite a long time. I’m happy with it and very surprised with the power. Definitely as powerful as a gasoline model. Well done, DeWalt.”

Best heavy-duty string trimmers

EGO Power+ 15-Inch 56-Volt Lithium-Ion Cordless Brushless String Trimmer

“I already have a Worx trimmer, and it’s a good trimmer for the low price. I needed more power for some areas of my backyard where there are stubborn weeds that the Worx would choke on and fail to cut. I like the extra durability, double string, more power, faster charging, and longer run time of this unit. The variable speed feature is really nice. It probably extends the run time, and why use it at full power when you’re only trimming grass? The manufacturer thoughtfully added padding to the forward handle for comfort and absorbing vibration during use.”

Greenworks Pro 16-Inch 80V Cordless String Trimmer

“This is amazing! We have been using this weed eater on tall grasses and weeds in our orchard. It eats through the grass without stopping! Lasts a full hour plus, even with the heavy growth. Everyone who uses it is impressed at how much power it has and how long the battery lasts. It is exactly what we were hoping for when we bought it. No more messing with mixing fuel, poor starting, fumes, and winter storage or maintenance that our old gas model required.”

Best string trimmer and sweeper combo

Black + Decker LCC140 40-volt Max String Trimmer and Sweeper

“I love the fact that this is battery operated and you get two gadgets for the price of one. Both the trimmer and sweeper are lightweight and reasonably quiet. The battery, once fully charged, lasted long enough to use the trimmer and sweeper to trim our quarter-acre yard, and it still had a charge a week later when I used the sweeper again. If you’re questioning whether or not to buy, do it!”

Best gas-powered string trimmer

Husqvarna 128LD 17-Inch Straight Shaft Detachable String Trimmer

“This is the second one I purchased. Purchased the first a year ago and used the heck out of it. I live on an acreage, so I have a lot of trimming — and not easy trimming like a suburban home. It has to go through a lot of thick weeds, doesn’t get clogged easily, and seems to have plenty of power. Worked so well, I purchased a second unit for our lake home.”
