Ok, So I seriously debated as to whether to buy this Saw or not as it looked too good to be true. Well I needn't have bothered its excellent. I bought it to cut up an old oak tree which had been fallen for a number of years and was well seasoned. The trunk was 30 plus inches in diameter. The saw just sailed through it not loosing power at all. I struggled to start it the first time I used it but since then it has not been a problem. If you are thinking of buying a saw of this size then you will struggle to get a better saw for the price. Delivery was excellent also, and no problem to assemble the Bar and chain
