The Black & Decker LST300 12-Inch 20-volt Cordless Trimmer and Edger already has accumulated a lot of great views, drawing our attention to test what so many users like about this weed eater. Based on our tests, this weed eater is best for the casual gardener, or those that use this tool for light lawn maintenance and not in any professional or heavy impact applications.

The Black & Decker LST300 12-Inch 20-volt Cordless Trimmer and Edger is light-weight even with the battery on board, making it easy to use around the yard. Please note that those over 6 feet or taller, might find they have to bend over more a bit more with this weed eater due to the compact nature. The 20-volt battery does provide up to 33% more runtime than previous models but is still not robust enough to hold hours of use, and it will take a few hours to recharge. We found at best, it can provide about 30 minutes of continuous use. If needing this for thick turf and weeds we found this to not be a sufficient tool to use.

Verdict: It is very affordable and is absolutely appropriate for small lawn maintenance work.

Verdict: Gas Powered – But Not Too Loud or Heavy. The Husqvarna 128LD 2-cycle gas string trimmer is a best and most versatile machine that is made to suit your medium or home yard.
