Rated 2 out of 5 by MS 171 Started out being a great saw. It cut the wood with ease. Then after using it a few months it started to loose power. Turned out the motors pistons somehow got scarred. Luckily I bought the oil that gives it another year worth of warranty. Well worth it.On the second engine and having the same loss of power.Saw is light weight and great out of the box but longevity not worth the hassle.The chains dont last long. August 9, 2016
Rated 1 out of 5 by MS171 Chain Saw quality is not good I just bought the save 7/23/2016 and already having problems. I ran it less than 25 minutes and the chain loosen which is kind of sad. There are reviews on here about the quality of the chain not being that good and they are right. I figure no problem I would loosen the nut that holds the blade so I could tighten the chain. The whole stud wanted to come out not just the nut. The blade was even stuck to the stud. I had a hard time trying to get the blade to go back in it place. I got everything back together. Since this was a dude on the start that means it will be a problem saw. I am hoping to get a refund and go buy a competitors saw. This saw was replacing a small saw of the same size that had gave up it fight. That saw came out the box with no problems and the chain did not loosen in less than 25 minutes. I would like to give ms171 a negative number of stars but that is not available. I hate to give a negative review I would rather leave a positive review. I bought a larger Stihl last year. It is a better grade than this one. But even the larger Stihl is not like the old 041 Farm Boss that I inherited. July 25, 2016
Rated 5 out of 5 by Great saw Works like a champ, handles great, love the features. Good saw for around the yard. July 25, 2016
Rated 4 out of 5 by A bit underpowered for trees over 6" Nice features, easy starting, easy to use safety brake feature, but a bit underpowered for a little larger trees. Would recommend stepping up to a higher powered farm saw. July 17, 2016

Rated 5 out of 5 by Awesome Awesome saw for around the home. I have used this saw to help heat my home this past year. I should have bought the next size up, but have no complaints. It definitely did the job. May 8, 2016
Rated 5 out of 5 by Light weight and tons of power - very reliable I have used this saw to cut down several trees in the 4-6inch size without issue. It has fired up every time I needed it, and ran particularly well in cold weather. I find the light weight is awesome for getting the job done. I am extremely pleased with this saw and am glad I chose to go with it. I really cannot emphasize enough how solidly built this saw is, it has handled everything I have thrown at it with ease.
