Corded electric cutters produce less noise than gas-powered ones. Hence, they are more pleasant to operate and more pleasant for your neighbors as well. If you prefer this type, look at the wattage of the device: higher wattage means more power. Since they are plugged in, the distance you can cover is limited. Also, you run the risk of shocking yourself and destroying the device if the electrical cord unintentionally gets caught in the blades or strings.
