Black and Decker NST2118 Cordless Nylon Line Trimmer / Edger First Impressions:
I live in a typical suburban house on 1/5 acre. I wanted a lightweight, cordless trimmer to cut the weeds along the backyard fence and house. I purchased this one 6 May 2013.
The only difficulty I had assembling the NST2118 was pressing the guard onto the trimmer because it was a tight fit. I'm 6 feet tall and there is still 1 inch of adjustment available on the handle/shaft for a taller person and over 7 inches of adjustment the other way.
I charged the first battery overnight. The next day, I was able to trim the weeds and some grass with dirt packed around the roots in the front and back yards and alley with only 1 battery. The backyard fence and house are cinder-block, concrete and stucco so I did not try trimming around chain link. I also did not do any edging. When I finished, the battery was still going strong.
The only problem I had was about halfway through the job the nylon line started to unravel on the spool while still inside the auto-feeder. It took me a couple of minutes to remove the spool and tighten the line by cupping it in one hand and turning the spool with the other. It did NOT wrap around the base of the trimmer like other auto-feed trimmers I've read about.
Finally, keep in mind that most battery-powered tools will not be as powerful as corded ones. Still, the NST2118 cut through several 1/4 inch diameter weed stalks (although it took me about 30 seconds of trimming for each one). Tips:
1. Follow the directions on battery care, charging and safety in the manual. 2. Store the batteries at "room temperature" (about 70-75 degrees Fahrenheit). Storing most types of batteries at extreme temperatures (outdoors, attic, garage, etc.) will reduce the battery lifetime. 3. Don't slam the bottom of the Automatic Feeder on the ground like the old style "bump feeders" because this could damage it. Pros: Lightweight. Works great at trimming. Long battery charge for a typical residential lot. Cons: Nylon line started to unravel on the spool.
