For those whose trimming needs are light, the inexpensive Black & Decker ST1000 electric string trimmer may be a reasonable option. At $25, it's easily the cheapest trimmer covered in the sources we researched, and at less than 4 pounds, it's also the lightest of the bunch.
Owners say this compact and featherweight trimmer is maneuverable, and the bump feed system works well. However, unlike the top-rated Stihl FSE 60 (*Est. $110) , this corded string trimmer can't handle heavy-duty weed cutting. Users say it's under-powered and slow, and we also read some complaints about its durability. Another quibble many users have is that the ST1000 doesn't include a guard to keep grass trimmings from spraying all over a user's clothing.
The Black & Decker ST1000 has not been included in any professional tests that we found. However, it does receive positive overall ratings from more than 250 users at Amazon.com and HomeDepot.com.
The Black & Decker ST1000 corded electric string trimmer receives more than 175 reviews from owners at Amazon.com, with an average rating of 4 stars out of 5. Most users consider this lightweight, easy-to-handle trimmer a good value for the money, but several complain about its low power and short lifespan. The lack of a guard is another commonly cited drawback.
