Query: pole saw review

Black & Decker 18-Volt Cordless Electric Pole Chain Saw, 8-Inch Bar #NPP2018..Saw was easy to use and battery life was good. had no problems through limbs up to around saucer size. nice storage case, if cutting alot suggest second battery to keep on hand. My only complaint was no self oiling system, which was no problem but you had to remember to keep oil can handy and lube often.
