Black & Decker 18-Volt Cordless Electric Pole Chain Saw, 8-Inch Bar #NPP2018This cordless pole chain saw saved us from paying a professional hundreds of dollars to cut down a diseased tree. It was over 30 feet tall. We reached out of the second story window and was able to cut some branches. With a ladder we were able to cut the balance top branches. It saved our energy to cut the large branches and trunk with a hand saw. Without buying a regular chain saw, this was worth every penny. It will used in the future over and over again. Thanks to the wise inventor.
