My property contains several decorative areas that are made up of bricks and rocks. It is very difficult to access these areas with the lawn mower and it is necessary to use a trimmer to keep these areas looking nice. I decided to purchase an electric trimmer because of how heavy the gas trimmers are when the reservoir is filled with gasoline. I am very happy with my purchase. You will need a long, heavy-duty extension cord to run your trimmer. My electrical outlet is no more than 100 feet from any location I need to trim. This would not be a good investment if you need to trim grasses or edge your lawn much more than 100 feet from the electrical outlet. I find that this trimmer is powerful and works well. I have used it over several seasons and it is still going strong. I am able to trim a large area in a short amount of time and keep my lawn looking nice all summer lawn. I highly recommend the Sun Joe trimmer. It is well worth the investment and should last for years to come.
