Rated 5 out of 5 by from Strong engine, handles great I've cut through 6 cords of wood so far with the 391 and love the power! I have a 25" bar and have cut through pine logs thicker in diameter and it never bogged down. Plus the weight of the saw isn't overbearing. My back slightly aches after cutting through a cord, but I've found that the weight of the saw helps with cutting through the logs. The 25" bar is a great length for being able to de-limb without having to bend down.

Rated 5 out of 5 by from Powerful saw, great weight to horsepower ratio and bullett proof design. I bought this saw to be my mid sized saw as I have a 291 with an 18" bar for small jobs and a Magnum 441 with a 28" bar for larger jobs. Being that I burn wood year round for our house and cabin I needed a mid sized saw for medium sized jobs/trees. This saw is amazing when equipped with an 18" bar and a rapid cut chain, it never bigs down, has a high chain speed, and pulls through any type of hard wood with ease, Oak, Hickory, Maple, Walunt, Ash, Cherry and rips through soft wood like butter. I have used this saw for 8 hours a day 4-5 days a week and it continues to amaze me with its amazing power to weight. You will not regret this saw as it is a great vallue and is the ideal all around "go to saw".

Rated 5 out of 5 by from Cut like a dream I have just about every budget saw known to man. This is a much better product by far. Fell 5 trees with it so far and one giant oak that fell on its own. Started every time and flies threw everything I have thrown at.

Rated 5 out of 5 by from Great powerful saw Ok, I've had the saw for 3-4 years now and used it each year.Saw really woke up after the first couple hours of use.With a sharp chain it chews through pretty quick...even hard maple.Starting after few months of storage isn't an issue...may take 3 -4 pulls and stall out if cold weather. Then starts and runs fine. Typically starts 1 pull after been run and warmed up.Most people problems with small engine equipment is ETHANOL fuel and /or improper gas/oil mix.Before owning any small engine equipment, find a gas station that sell ethanol-free. Get a can just for ethanol free. Trust me folks, pay the extra couple bucks. Your lawn/small engine gear will last much longer, run stronger, and you wont have expensive carb problems after sitting all winter.This saw with a 20" bar will tire you out if you're not use to wielding this lightsaber all day.

Rated 2 out of 5 by from Great saw... as long as the ignition module works. Bought this saw for my father as he cuts alot of wood on his farm for heating the house. Lots of hickory, oak, ash, etc. So I wanted to get a good strong chainsaw that would cut quickly through these woods and then he could use the lighter saws for small stuff. I chose Stihl because of the reputation for service and quality. Not long after we got the saw we put it to work. Break-in went well and the saw performed as expected and better. It was actually a pleasure after using some... lesser saws... to cut large logs to use one that was meant to do the job. Saw started easily, ran well, and we were pleased. Until a few months later, that is.For some reason the saw wouldn't start. I have to say that we always follow manufacturers' recommendations for oil types, service intervals, operating procedures, etc., especially with brands and equipment we aren't familiar with. After a few go around with local service folks about starting it incorrectly, improper fueling, etc., we took it in for service. Since it was under warranty they weren't exactly happy to see us, but eventually they took a look at it and figured out the ignition module was bad. After replacing it the saw worked just fine again.All would have been well if that had been the only time it happened, BUT this has happened at least 4 other times. I purchased the saw in 2013 as a gift for my dad. After the 3rd time Stihl replaced the entire power head at no charge. It has happened twice again since then. This last time the tech replaced only the spark plug and returned a non-functioning chainsaw to my father. My father, no slouch in home small-engine repair, got fed up with the service and bought a non-OEM ignition module and put it in himself. Hopefully this will end the problems.So in all, we are thoroughly disappointed at the reliability of the saw in general. Performance is good, but what use if a good performing machine if you can't even use it? I don't know if it's just the MS391 that has these issues, or if a bad batch if ignition modules came through, or what is going on. I know my father stores the chainsaw in it's case in the barn, so saying it is improperly stored is ridiculous, especially after watching plenty of other people with Stihls do almost no maintenance, keep them in the back of their pickup with no case, and use them day in and out with no problems. Might be a bad model, might be a bad module design, either way be very careful with what you spend your money on.
