I recently bought a Black & Decker cordless pole chainsaw and had a chance to use it this morning. I would rate it as a good tool. It is normally about 10 ft. but will extend to 14 ft with an insert (included) between the handle end and the saw end. It is light and will cut a decent seized limb (B&D says 6" but I pushed it). I used it on a roof and had no problems keeping my balance. The only problem is that the battery did not last as long as advertised and takes too long to recharge. I will get another battery. I bought it at Lowes for $129.00 + tax.
