I purchased this trimmer last year. It has already died, but I was so frustrated with it, that's OK. (if interested, you can see my 3-star review right after purchase)

The automatic feed never worked right: I had to continuously unplug the thing and advance the line: the auto feed depends on a sprocket system that allows the spool to advance: but as soon as dust gets inside (which happens immediately), the sprocket binds up, and the line does not feed out.

Also the black guard that protects the user from debris getting kicked back is fastened with one small screw in soft plastic: the vibrations caused by normal usage caused this screw to strip out in the second use. Getting the item back to B&D for warranty repair would have cost me more than a new unit, so I did my own repair last year. The construction seems rally cheap and therefore potentially unsafe to me.

This trimmer has been nothing but trouble since I bought it. It's better to use a less-polluting electric trimmer (not gas powered), but this one is not well made.

We got this thing right after it came out. It wasn't and automatic feed so much as it was an always feed. It basically just always fed out line, using it up quickly. It ended up being cheaper to buy a new weed eater (not this brand or with that feature) than it was to keep buying line. About the only positive was the service from the company. They'd send replacement parts to us when we asked at least for the first year.
There was a small plastic piece which controls the feed of the line. It was constantly wearing down and melting. This just didn't work. The replacements had a piece of metal on it to try and help, but it didn't really do much.

A portion of my yard was not accessible all spring and summer due to construction. The grass and weeds grew to 4' tall. Tried this trimmer and edger, which does not state it is a weed wacker, and did it ever take care of those weeds. The string feeder works great, bought extra spools but did not need them for this job. It is easy to handle (I use a cane) and had no problem at all. No gas smell, not noisy. I cannot say enough good things about this Black & Decker product.

Horrible product. Almost caught fire from burned out motor on first useage. It started smoking after six minutes of light use. Do not buy. Buy one of the Black & Decker grasshog models instead. They need to recall this thing before someone gets injured.

I am very pleased with the ease and strong performance of the B & D edger and trimmer (#ST7700). I have both Bermuda and St Augustine grass and it cleanly cuts with out tearing up stolons. I use it on a large bed of primrose and it cleanly cuts the tough runners. In addition to the light weight the handles make it east to switch from trimming to cutting.

This trimmer is very similar to the old B&D I had which was great until, for some unknown reason, I banged it on the ground to advance the string which broke the auto feed mechanism. Anyway, I ordered this trimmer and have used it several times. It works great - just like the old one! It is light weight and easy to handle. I have a long driveway and sidewalks and I can edge everything quickly. Just don't bang it on the ground!

This trimmer replaces a B&D ST1000 that died after 7 years. The new trimmer makes short work of our small yard, unlike the old trimmer this one never booges down in heavy grass or anything else for that matters. It does seem to go through string faster, but that may be do to the fact that it is more powerful and faster than our old trimmer. One more thing this trimmer will throw rocks and dirt into the air at very high speed when rotated in edger position, that may be true of any powerful trimmer or this trimmers guard design.

Black & Decker is a reliable name whose products I have purchased over the years. I actually bought this particular product as a standby, but use it more than I thought I would. I have a very small lawn in the front and back and actually have someone mow the front lawn for me. However, my back lawn's grass is kind of weak and his equipment is too powerful, it always killed some of the grass, especially around the edges with the trimmer he uses. I decided to do it myself so I purchased this lightweight trimmer and it serves my purpose. My grass is in better shape than it was and I really don't mind doing such a small lawn this way. In early spring when the grass has started to grow, before this person starts his mowing season, my trimmer comes in handy to give a finished look to my front lawn. Again, I am using this on a very small lawn and it does a great job. Let's not forget it's intended purpose, it also does a great job trimming and edging.

I bought this product before traveling for 10 days. When I got back, I set it up quickly without screws and started using it in about 10 minutes. Worked great, the autmotatic feed really works. I bought the aditional pack of 3 replacement string. Some commented on this site that the string runned out fast, I have not experienced this issue. I will use it some more and comment here. By the way, I had a jungle waiting after the trip and the trimmer had no trouble cutting it all. The edger function is so easy to use.

The one I had not only didn't last very long, but while it did work, the power and the .062" string was very underwhelming. If you don't want to use a gas-powered weed whacker, look for the Ryobi electric trimmer with the .080" line.
