    Don't buy this product: Line advance system fails. Should hava a zero star option, one is being too generous
    From day one it didn't last through one mowing of the lawn. refilled spool and then didn't advance at all? This product should be recalled. I usually need to take the cap off, pull the spool out and manually advance the line and put the cap back on. Should have returned it the first day of use in retrospect.

    Nothing to like if it doesn't work correctly. It has motivated me to do research first before buying a replacement for this piece of junk. Agree it's light weight for tossing in the garbage.


    line advance system This is not a green product if everybody is throwing it away. Might as well get a gas operated trimmer that works

    It is a piece of garbage. THE LINE FEED DOES NOT WORK. I am an engineer and ex mechanic, I patiently messed with the new spool for hours. I threw it in the garbage out of frustration, and that is where it belongs. Once again - DO NOT BUY THIS PRODUCT - IT IS A PIECE OF CRAP

    It is light weight so it was easy to toss in the trash


    line feed -DOES NOT WORK

    Uses too much line
    I have been very careful to wind the line neatly, but at times it has gone through a spool of line in 10 minutes.

    Has good power.


    Auto feed system needs to be fixed.

    I am no longer happy with B&D products
    The 7.5A string trimmer uses too much string. I went through 2 spools and still have not finished my yard. I plan to return this product and will seek elsewhere for a trimmer I can depend on and that will not cost me $29 every week to use.

    The trimming is ok


    I do not like having to stop to fix the string and the string disappears way too quickly. I have never had so many problems with B&D before. I was a big fan, but not any more. The two string line trimmer was also a waste of time and effort.

    This product should be recalled
    The low rating for this product is well deserved. It uses line at a rate that is completely unacceptable. Just to give an example - the original spool was gone before I could finish one pass of my lawn. I've had this product for about 4 months, and I've already gone through nearly two 180' spools. I can't go more than 30 seconds without the line fouling and I have to stop, disassemble it and rewind the line (if it's not out already). There is no excuse for this. I'd return it but I have lost my receipt, so I'm stuck. As Black & Decker's top of the line electric trimmer, this product is a joke. I'm hoping someone at B&D will see this and respond.

    My grass is greener due to all the green trimmer line littering it.


    I'd give it negative stars if possible.

    Great product!
    After reading the many negative reviews, I was determined to return the trimmer for a refund. Before I returned the trimmer, I decided to remove the spool head to see how the "Automatic Feed System" (AFS) worked! Let me pause to explain that I'm a retired professional engineer and therefore, I'm just naturally curious about how things work! I believe that if one understands the logic behind a design, they will also understand why a device might not work or how one might make it work. First, let me say that this trimmer was obviously designed for heavy trimming! The principal behind the (AFS) design is this: When the cutting line meets resistance , the trimmer will experience a force sufficient to pull the line from the spool and the spool will slip. When this happens, a roller cam under the spool will advance along a path on the underside of spool. Centrifugal force causes the pivoted roller cam to ride along the inside of the track as the spool slips and line is advanced.

    Now, having explained how the (AFS) works; you can see that if too little resistance is encountered while trimming, then the line will not advance and if too much resistance is encountered, then the line will advance continuously, causing an unacceptable rate of line usage. It's also important to note that when replacing the spool, the roller must be positioned such that it will fall inside the track and that the spool is pushed in all the way until you hear it snaps tight. To verify that the spool is properly inserted, pull hard on the line. If the spool is properly inserted, you will not be able to rotate the spool or advance the line. Solution: (1)If the line won't advance: temporarily position the trimmer so that the line hits the ground or another fixed object to advance the line. (2) if line is being consumed at an unacceptable rate, decrease the load on the trimmer line by decreasing the rate at which the weeds are being cut and work at a slower pace.


    The AFS doesn't work well, or not at all, under light loads such as is commonly encountered when trimming after cutting the lawn!

    Don't Buy
    I used this string trimmer for the first time to edge my driveway, it is a very powerful tool with a wide cutting range. Although the automatic feed spool (AFS) is very poorly designed. Before I was even 3/4 of the way done with my driveway the spool had come undone. It is noted that if the spool feeder becomes jammed or undone, read the manual. I did that, I read closely the directions on how to put the feeder together again. I, personally could not figure out how to re-piece it. Not to mention, the spool runs out extremely quick. As I said, 3/4 of the way done the spool became jammed, it had also gotten to be really short, I had already used most of the string, before I was even finished.

    -Powerful Tool -Wide Cutting Radius


    -Poorly designed AFS -Small amount of spool for the feeder

    Self Feed sucks
    I purchased this product 6/22/13. Used it twice & exchanged it because the self feed system failed. I used the 2nd unit for less than a day when the self feed system failed. The people at the big box hardware store told me that my return (of 2nd unit) was the 4th this week.

    Light weight. Powerful. Easy to use for edging or trimming.


    Self feed system failed. Took more time to manually feed the string than worth.

    Do not buy
    I purchased this as a replacement for a cheaper B & D trimmer (it lasted 8 years). This one broke after 2nd use. I exchanged it, new unit broke after 1st use. The AFS does not work. The people at the store said they have had almost more returns on this model than all other models combined. R & D really needs to field test these products in the real world. I have many other B&D products, this is the only one I have ever had an issue with.

    Higher "strength" string as compared to lower end models


    Not reliable.

    I can't believe the cutting line is already used up and I haven't even finished edging my yard !
    I just took this out of the box-brand new. I edged my small back yard and was working on the front yard when the cutting line was gone. I opened the spool and found it empty. What the? Does this only come with enough line to edge around 100'? Now I need to buy replacement line after 30 minutes of use. At that rate it would be cheaper to hire a landscaper. I'm wondering if this is an abberation or should I just return it and try someone else's.

    Lot's of power and a wide cutting area.


    Line runs out in minutes-really !
