How We Research
Every guide on SundaySmarts starts with one question: will this product work for the person who is shopping for it? For our string trimmer guides, that means your yard, your edges and the battery you plan to run.
Here is how we answer it.
1. We start with the yard and the battery
Trimming along a fence, edging a walk and cutting thick weeds ask different things from a trimmer. A brand's batteries also tend to fit only that brand's tools.
We check the battery voltage, the cutting width and whether a model comes tool-only or as a kit. When your yard limits the choice, we say what to look at first.
2. We compare specs and features
We look at battery voltage, cutting width, motor type, shaft style, line feed, weight and whether the shaft takes attachments. We also note the run time the maker lists.
WORX, EGO, Greenworks, DeWalt and Milwaukee describe their trimmers in their own words, so we name the brand for every claim. We also note the warranty terms the maker lists.
3. We look at buyer feedback
We read through what buyers report after using a trimmer. We look for patterns, like line that jams or breaks, short run time, batteries that fade, heavy heads or hard line loading.
One angry review doesn't sink a product. A pattern does.
4. We score each product
Our score weighs specs, features and buyer feedback against what you're shopping for. A trimmer that's great for one yard may score lower in a guide written for another.
Scores spread out on purpose. A 10 is rare.
5. We keep pages up to date
Products change, and some disappear from stores. Makers sell trimmers with similar names that differ by battery and kit, so we check each model number and what is in the box, and we only link new units.
When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every trimmer we cover.
Our guides don't replace the maker's manual. For line, guards, eye protection and battery care, follow the maker's directions.
We don't promise that any trimmer will cut thick brush or finish your yard on one charge. When a maker makes a power or run-time claim, we label it as the maker's claim.
