Rated 5 out of 5 by Trimmer works great with Lithium Ion battery Purchased this trimmer because I didn't want the hassle of a cord being dragged around my large lot. Also, didn't want the maintenance problems faced with a gas/oil engine. This battery powered trimmer meets my needs. April 11, 2014
Rated 3 out of 5 by Better trimmer than I thought a rechargeable would be. The trimmer was easy to assemble and once the battery was charged it was ready to go. The battery seemed to take longer to charge than I thought it would take but it was not an unreasonable time. I have only used gas power string trimmers before so I didn't know what to expect from this. For a rechargeable unit, this had better power than I thought it would but not quite as much as a gas powered unit. The trimmer did a good job trimming grass but I suspect it might have a harder time with heavier weeds and brush which a gas powered unit can get through. The trimmer head is reversible and has a wheel on it so the unit can be used for edging. Converting to edging mode was easy and it did a good job edging my lawn but it did require me to be careful to stay along the edge. The battery life is about an hour so if you have extensive yard work to do, this might not last long enough so you might want to consider a second battery. Overall, this trimmer does a good job for grass and other light trimming. March 6, 2014
Rated 5 out of 5 by B & D Trimmer can't be beat! The Black and Decker 20-volt lithium-ion trimmer has exceeded my expectations. Almost straight from the box I was up and going, just the handle and the trimmer guard have to be assembled - no tools required. A full charge on the battery and this thing can match up with the 2-cycle it just replaced, with no mixing, choking, or pull starting. Very light weight and a dream to use. I would very much recommend this product. August 31, 2014
Rated 5 out of 5 by Powerful, Light weight Excellent tool. Really does the job. Rotating head for edging is a big plus; guide wheel is a big help. I still haven't figured out how the automatic line feed knows when to kick in, but it does. Better than a bump feed. Battery has never run down on me yet. Recharges quick; probably won't ever use my gas trimmer again. March 13, 2014
Rated 4 out of 5 by Battery needed to be replaced I love this edger. After 4 months of ownership, the battery failed. Had to be replaced through the warranty process. Took a couple of weeks to locate my receipt. Then the battery was on back order, which tells me they are having production problems with this new 20v battery. Took 2 more weeks to reroute a battery from a different distribution site to me. So after 6 weeks I have it working again. I just love it. Just wished the battery was more reliable. But the next time it croaks, I'll have the receipt ready and if it is backordered, I and the repair center will know to find one somewhere else in the country and get it to me in a more timely manner.
