Recently bought an MS120 battery chainsaw for smaller work (i.e., pruning, and cutting of thinner firewood) without continuously breathing the exhaust fumes of my larger gas-powered saw. I am positively impressed with the MS120 performance. It is easy to handle and a great tool in situations where I either don't need more power and a larger blade or don't want to use a heavier machine. My only qualm is that Stihl sells these units without the appropriately sized chain sharpening tools as they (at least used to) do with their larger gas-powered saws and that the dealer I bought my MS120 did not warn me.
