From the Manufacturer
No bumping or turning off the motor to hassle with hand feeding string; Black & Decker's 18-volt cordless string trimmer features the company's exclusive Automatic Feed Spool (AFS) system that automatically advances cutting string without bumping. By letting centrifugal force feed the trimmer line as it is needed, you get a smooth consistent length of line for optimal performance. Battery-powered, this cordless string trimmer has the capacity to trim grass after mowing for up to a 1/2-acre home site on a single charge of both included 18-volt batteries. Quiet and easy to start, the unit requires no gas, oil, or tune-ups. The Grasshog's Groom 'N' Edge head rotates 180 degrees to convert the trimmer to an edger with a push of a button. When used as an edger, the flip-down edge guide keeps the Grasshog in line with sidewalks and driveways. A secondary handle adjusts for increased comfort and control. A lock-off switch prevents accidental start-ups to ensure safe usage every time. Your purchase includes a trimmer/edger, two 18-volt batteries and a charger. Black & Decker includes a 30-day no-risk satisfaction guarantee and full two-year warranty is provided.

Customer Reviews

Can't do the job
I bought this hoping to replace an old corded trimmer, but the Grass Hog just did not have the juice to do the job. The batteries take 9 hours to charge! I have never heard of a rechargeable battery taking 9 hours, but that is what the instructions say, and the instructions were accurate. The 2 batteries combined could not trim our .2 acre yard. You will be lucky to run the trimmer for 10 minutes per battery, then you get to wait for another 9 hours to have a charged battey. I returned mine and will buy a new corded trimmer so I can do the entire yard in one day.

Trimmer
Does a good job as a trimmer and edger. Light weight makes it easy to handle. Battery doesn't last as long as I would like, however, with the two batteries supplied I am able to finish my yard.

Good Overall, But Could Be Better
I bought this product in the last week and have used it twice since then.

It comes with two identical batteries. At first I was suspicious about the battery life - why include two, unless one won't last? Fortunately, that wasn't entirely the case. Each lasted at least a good 20 mins (that's about as much edging/trimming as I needed to do). Over time I could expect the battery life to decrease, and other people might have larger yards. So I could see why they included two. But I still would have expected a bit longer life out of just one. After all it's not a very small/light battery in the first place. Charging takes a good 9 hours as the instructions say. I can't say anything about the long-term life yet.

Performance was adequate, but not stellar. It'll whip through the average blades of grass without problem, but don't expect it to do much on low-lying weeds or thicker plants. Several passes or very slow movement will be needed to get the full result. It's a little on the heavy side to be carrying around for very long. The front handle helps a bit, but I got fatigued after my 20 minute run.

Usage instructions are lacking. The battery charger has a thorough instruction sheet, but the product itself does not. It's all done in a few small pictures - most likely to bridge the language barrier. But those pictures are vague at best. I had to figure it out by trial and error. The adjustment to go from "edging" to "trimming" was nice and convenient with a twist of the shaft.

As with most devices of the kind, you shouldn't be trimming with exposed skin or without eye protection. Debris has a tendency to go flying out of this thing, based on the mere nature of what it's doing. I noticed a few other reviewers got some injuries, which I don't understand. Hello?!?! You're holding a device that's whipping a cord around at a high RPM, with it impacting small stones & pieces of brush. Wear pants and keep the kids away!

If you have a small suburban yard that requires light to moderate work once a week like I do, you should have no trouble with this product. Anybody else should look elsewhere.
