    Like a previous reviewer.I signed up just so I could express my disgust at Black and Decker for cheating their customers with this sub-par product. I think the trimmer is great - light and easy to handle. HOWEVER, THE BATTERY IS A COMPLETE RIP-OFF. IF IT LASTS 5 MINUTES YOU'RE ONE OF THE LUCKY OWNERS. IT'S A DISGRACE.

    The trimmer is easy to use

    Not lived up to it's Hipe-poor performance and expectation
    24 Volt Battery string trimmer/edger. The battery dies out in less then 10 minutes of usage. Have to wait to long for it to charge. Always have to pull out the gas string trimmer to finish the job, sad :(



    battery time and replacement parts. The charger stop working right after warranty and trying to replace it has been a nightmare. I have gone through two that do not work!

    Used once. Was hurt 5 times in 5 minutes.
    Kept getting cut on line that fed out but, obviously the cutter didn't cut the extra line. Pieces of line would finally cut off and hit me in the leg or thigh, and one piece of line got me in the upper arm (six inches higher and it would have cut my face). Piece of junk, waste of money, and dangerous.

    The only 'pro' I can think of is how easy it will fit in my garbage can.


    Doesn't feed line correctly. Is dangerous, and you can get hurt.

    5 min use, 11 hrs charge
    First charge I left it on charger 24 hrs, got 5 minutes use. It's going back. How did this ever reach the store shelves.

    It's a good idea. It worked well for 5 minutes


    I can't trust Black & Decker any more, or the ratings, must be some factory rep bumping up the stars to two. How can I put in negative stars.

    Where's the beef? No battery stamina whatsoever! Shame on B&D!
    Love the ergonomics, but I can't get very far on one battery. This should have come with [2] minimum. This will not take the place of a gas trimmer.

    Handles well, adjusts to comfortable setting. Easy on the arms because it only works for [20] minutes until battery dies.


    I have 24V drills that use the same batteries, and they work fine. These things are either faulty or someone's idea of a cruel joke. Why even bother, unless they were going to put [2] batteries and a quick charger included with it.

    Edit; Product even worse than imagined
    I thought I could use the trimmer with a sturdier line, but now the autofeed mechanism fails completely, spitting all the line out immediately. I will be returning this tomorrow.

    worked well twice.


    Everything. Particularly the autofeed mechanism. DO NOT BUY!!!!!!

    I made a Black and Decker account just to give this product a negative review.
    I feel like the Black and Decker engineers failed on many levels for this product. I was disappointed when I first opened the box, and saw I had to wait 11 hours for the battery to charge. Annoyed when the pre-wrapped line spool was tangled out of box, so the feeding mechanism failed. Ticked when once restrung correctly, the whole spool was worn down in 5 minutes, and absolutely furious once I realized a sturdier .065 stock line was incompatible with the trimmer (The blade was set too far from the base to snip the sturdier line as it extended. Flipping the blade around inside the guard allowed me to use the sturdier line). With the sturdier line, I was very pleased with how the product worked, until the battery died shortly after. While I understand that it is a battery, I feel like for the price and 9 hour charge time, Black and Decker should have shipped two batteries with this product.

    Works well once modified to handle a sturdier .065 line.


    Black and Decker needs to teach the children in China to properly wrap trimmer line if they are going to advertise their spools as "less likely to tangle." The line itself is really poor. Use a different brand stock and adjust the blade. 1 battery is insufficient to trim an entire yard. Black and Decker should supply two, and even then those with larger yards should not realistically expect this product to meet their needs. Minor issue: The trigger is surprising awkward to hold; the thumb safeties are difficult to engage and annoying for stop-go-trimming.

    Tired of replacing the string
    The battery life is what it is. I bought a second battery and got over it. I'm into my second season with and now I don't think my trimmer is releases the string correctly. Either the replacement spools are flawed (B&D likely re-sourced to China) and aren't made correctly OR the release mechanism is worn out. After resetting a new spool, a bunch of string flys out and either I cut it or re-spool it. Either way it is not the badass trimmer I bought 3 years ago. Oh yeah the manual was no effing help. Each spool indicates this as if to taunt to me that I need to back to manual.

    Its light, with 2 batteries I get the job done.


    The string debacle mentioned in the review.

    High Expectation / Low Performance
    We had two gas trimmers which were too heavy for me to operate. I do several yards in our neighbourhood, and as I'm of short stature, I needed something easier to manage. B&D, in our minds, had a good rep so we were prepared to pay a bit extra. After charging the battery as per the instructions, the first time out I was very happy with the results. However, we noticed that the battery was holding a charge for shorter times each time it was charged. As I was doing three yards, I could barely get one yard done before the battery needed charging - for 12 hours each time - which meant that I could never get all yards done in one day. Eventually, I couldn't even get our own yard done on one charge. Besides that, the switch was faulty - couldn't turn the thing off. We resolved that by permanently fixing the setting with a plastic tie-back.

    Properly weighted and balanced for a short person (I'm 5'2""). While the battery was functioning at optimum, it worked great.


    Completely disgusted with the performance of the battery. Will never go with a Ni-Cad battery-operated trimmer again. Replacement battery is $90 - at that price, we decided to go with a different brand entirely. So disappointed with B&D over this waste of money.
