I sawed firewood for the winter in a week. The saw is good in business, the deadwood falls apart into chocks in an instant. Lightweight, excellent balance, comfortable in the hands. Vibration is almost imperceptible. The chain does not wedge, although I messed around with the adjustment of the auto-lubrication system, at first the oil was leaking. I didn't find any cons as such. The exhaust, however, is chadny - you won’t work in a shed for a long time.
