Rated 2.3 out of 5 by 130 reviewers.
Rated 1.0 out of 5.0 by Cheap piece of junk I only gave this a "1-star" because I can't select less............The design and workmanship are sub-standard quality. As you can see in the pictures, the string housing gear ate away the housing until it shifted far enough to lock down, at which time the "metal" motor gear ate the teeth off one side of the string housing gear. Don't waste your money, and don't go to Black & Decker website expecting to buy any replacement parts for the housing assembly, they don't offer those. But you can buy a screw for $.99. June 25, 2014
Rated 1.0 out of 5.0 by spool replacement $$$$ This product is terrible. I can't see how anyone could say this is a quality product. The auto-feed feature doesn't work. Anytime the string hits something like a wooden fence or curbing it breaks then it either doesn't feed or it sends out way to much and then snaps off in the spool. The actual spool breaks quite often so the little plastic pieces that are suppose to hold the line break or bend so badly they don't work anymore. After that happens it doesn't matter how much string is left you can't use it. Also the replacement spools are $8 dollars. I didn't realize when I bought this that you can't buy string and spool it, you have to buy the special auto-feed spool. I have only used this five times, I have probably trimmed a total of 50ft linear of grass, I have used 3 replacement spools. May 7, 2012
Rated 1.0 out of 5.0 by Junk! Don't waste your money! Auto-feed is a myth. The line jams constantly, forcing you to stop work, pull the thing apart, reset the string ... and you're good for about four feet of cutting until the line jams. Then you stop, pull the thing apart and repeat as above. At first I thought I was using line that was too thick but after trying different diameters I have concluded that this is a poorly designed hunk of junk. In addition, during it's brief periods of actual operation it is noisy and does a lousy job. Because of it's design it doesn't close enough to walls, stone fences and other objects to do a satisfactory trim. October 29, 2011
Rated 1.0 out of 5.0 by Save your money and frustration I cannot believe I have kept this piece of junk around for over a year. Today was the last straw. It went into the dumpster for good. The dual string sounded like a good thing. Too bad it doesnt work in reality. I have had to constantly take the stringing mechanism apart to get the string to come out. It works for a minute or two and then out of string again, or tangled? I have spent most of my edging working on getting the string to come out than I have actual edging. I use to like Black and Decker products but this is the 2nd time I have been burned. The first one was their coffee maker, but then I won't go into that right now. I have learned my lesson.

Rated 1.0 out of 5.0 by piece of junk cannot believe i was stupid enough to buy my 3rd one of these. This one just died this morning after less than a year. at one time all I would buy is b&d products but they are all cheap junk now. going to buy another brand and never buy b&d again April 6, 2013
Rated 1.0 out of 5.0 by POOR CHOICE, STAY AWAY! I've used grass trimmers from B&D for years. My last one gave up the ghost so choosing another B&D product was a no brainer...right? This is the worst trimmer I've ever owned, and I go back to when you had to hit the ground to release more cutting string. A fully wound spool runs out seemingly in minutes (I haven't a clue where it goes). Turning the head required a twist and a turn rather than a simple button and turn. Not a big deal but it just adds to the overall aggravation. Another problem is aligning the cutting with the grass edge. I don't know why but the cut is uneven and difficult to control. Sometime no cutting, then without warning it cuts a big divot. Does make for a nice trim at all. Not sure if I will be able to return it but I certainly will try. Would I purchase another B&D trimmer? Certainly, just not this model. Stay away from this model. May 3, 2013
Rated 1.0 out of 5.0 by I Can't Believe Anyone Has A Positive Review Of This Product DON'T BUY THIS TRIMMER! Yes, this trimmer is easy to assemble and use but Black & Decker really dropped the ball. We bought one last September and only used it a couple times for some light trimming. When I used it today on some heavier work it constanly jammed and coninusouly fed new line whether I needed it or not. It stopped working so I grabbed the box and receipt and took it back for a replacement. I got a new one and I'm taking it back tomorrow!!!!! I needed a pair of shears just to continuosly cut the non-stop waste of line that comes out and tangles. I only used a couple feet of line but the rest of the expensive spool was wasted. I barely got a quarter of the area I was working on trimmed. This trimmer really stinks!!! June 10, 2012
Rated 3.0 out of 5.0 by Good trimmer *if* you know you must... ... do some specific things: I say that because the Black & Decker auto feed is terrible. The Black & Decker auto feed is extremely unforgiving to hand wound spools. You must wind the line onto the spool *perfectly* as if a machine did it. Look at the spool that comes with the trimmer to see what properly wound line should look like. If you overlap the line even once the line will either not feed or it will shoot out everywhere. You *must* use round non-serrated .065" trimmer line. Only fill the spool about 1/2 to 3/4 of the depth, do not try to wind as much line onto the spool as possible. You must also soak the bottom of the spool and inside of the orange spool cover in WD40 or some such lubricant, all of the contact surfaces must be kept perfectly clean and smooth. When you mount the spool lines into the spool head you *must* keep the line snug, do not let the spool line unroll even the least bit. If it does unroll even the least bit you must make sure it goes back to being *perfectly* machine wound. You must also assure that once you have the line in and the spool mounted that the line is not bending upward (not up toward the inside of the sheath) but instead bending straight out to the sides or down to the grass. It takes some practice to learn how to wind the spools by hand and sometimes I still have to take the spool cover off because the line gets stuck and doesn't feed. If you can put up with learning this stuff this is an otherwise great electric trimmer that can handle some really thick grass. I even used it to cut some overgrown bushes and 1" thick vines growing up a tree. If B&D would make a manual feed version of this they would have a five star electric trimmer. I'm sure B&D is more interested in selling replacement spools, sort of like inkjet printers and printer ink. July 1, 2012
