Ideal for both post-mowing maintenance edging along hard surfaces like pavement, and trimming grass in hard-to-reach areas, this easy-to-handle automatic feed string trimmer from Black & Decker cuts a 13-inch path and has a 180-degree rotating head for simple conversion to edging work.

There's even a convenient cord retention system to guard against unintended unplugging of the tool while you're working.

1.0 out of 5 stars lasted less than 1 year - always a problem, May 21, 2007

By	B. Conover - See all my reviews (REAL NAME)

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.

1.0 out of 5 stars Automatic feed was Always feed, November 4, 2007

By	Robert P. Sterner - See all my reviews (REAL NAME)

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.

1.0 out of 5 stars Definitely not a grasshog, September 29, 2007

By	Lucinda H. "cyndylu" (Crescent City, USA) - See all my reviews

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.
