Best For

The Owner-Style Take
Opinion
My read: Black+Decker 20V MAX 12" String Trimmer (LSTE525) is not a universal recommendation. It earns its place when the use case is narrow and real: Small suburban lots (under 1/8 acre), light-duty trimming, and homeowners already in the B+D 20V Max ecosystem.
The reason to keep it on the shortlist is Sub-$130 entry-tier pricing for a battery trimmer. The reason to slow down before buying is 12" cutting swath is narrow vs premium trimmers. I would not treat the star rating as the decision; I would treat the yard, storage, maintenance tolerance, and five-year cost as the decision.
If you are deciding between this and EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S), start with the failure mode you are trying to avoid. Pick Black+Decker 20V MAX 12" String Trimmer (LSTE525) when the notes below describe your lawn more closely; pick EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S) when its compromises sound easier to live with.
Pick It Over
- Pick Black+Decker 20V MAX 12" String Trimmer (LSTE525) over EGO Power+ 56V 15" String Trimmer with POWERLOAD (ST1521S) when you want the cheapest complete kit and will not build a premium outdoor battery platform.
- Pick Black+Decker 20V MAX 12" String Trimmer (LSTE525) over DeWalt 60V FlexVolt 17" Brushless Cordless String Trimmer (DCST972) when its fit matches your yard better than the higher-rated alternative.
- Pick Black+Decker 20V MAX 12" String Trimmer (LSTE525) over Milwaukee M18 FUEL Quik-Lok String Trimmer (2825-21ST) when its fit matches your yard better than the higher-rated alternative.
Skip If
- - You are already locked into a different battery platform and do not want another charger and pack family.
- - 12" cutting swath is narrow vs premium trimmers
- - 20V platform lacks torque for thick growth
Five-Year Cost
Estimated five-year cash outlay: $200-$410. That includes the current street-price range plus string, blades or heads, and a possible battery refresh if this becomes your main yard tool; it does not assume a paid repair shop unless the category commonly forces one.
Black+Decker 20V MAX 12" String Trimmer (LSTE525): Editorial Assessment
The LSTE525 is the right kind of cheap: honest, light-duty, and complete in the box. It is not a gas replacement, and it is not the start of a premium outdoor platform. It is a small-lawn trimmer/edger for the person who wants to clean up beds, fences, and sidewalk edges without spending EGO money.
Pick it over Ryobi when the lot is tiny, the budget matters most, and you do not already own Ryobi 40V batteries. Pick it over Greenworks when the work is light edging rather than thick weeds. Pick it over EGO only when the cheapest complete kit matters more than platform depth, torque, and long-session runtime.
The feed language matters: this is EASYFEED push-button line advance, not a fully automatic head that senses line length. That is fine, but buyers should understand the mechanism. The published 20V MAX setup, two small batteries, and long charge time put a ceiling on the job size. If trimming takes 10-15 minutes, it is a bargain. If the yard has ditch banks, woody weeds, or a long fence line, skip it. Five-year ownership is cheap because spools and small 20V batteries are cheap; the tradeoff is that you may outgrow the tool before it wears out.
