Rated 2 out of 5 by Good for harry homeowner for smaller stuff Works great as an all around brush saw or for cutting smaller logs. Descent value for the power it comes with cause its pretty inexpensive. September 1, 2015
Rated 5 out of 5 by 12 loggers cords and a new 391 I bought this saw brand new just all factory I left the 18" on it for firewood been cutting with it everyday it is a great saw and its light and its got more than enough power I cant seem to bog it down it fires right up in two three pulls tops I really like how light it is and how good it is on fuel and bar oil I can cut for it seems like hours before I have to fill it up and sharpen it I will keep doing my wood and post another review in the winter let everybody know how its running August 24, 2015
Rated 5 out of 5 by MS 391: A fast, dependable saw for big jobs. I had two dead oak trees in Illinois that had to be removed with diameters of 40 and 52". The best offer I could get was $900 for an arborist to remove just the smaller tree. Instead I purchased a 28" blade for my MS 391 and called a few buds to help cart the logs away. Each tree came down easily and I cut them into 25" lengths. It took about four hours per tree from start to finish. This is not a light saw, but if you let the saw work for you it pulls itself right through the tree and you can go for hours. That saw never kicked back or lagged once, and the chain stayed sharp through the entire job. One tree alone paid for that saw! My guys saw how easily it was cutting and begged me for chances to try it out themselves. Is there a finer saw anywhere? I've not found it. August 14, 2015
Rated 5 out of 5 by i love the power i have a ms 290 and was wanting a bigger more powerful chainsaw i cut a lot of firewood some 30 plus inch logs and the ms 290 is good but lacked the power i needed to get the big jobs done so i got the ms 391 and love it so far its got plenty of power my only complaint is that its heavy but if you can over come the weight its a great chainsaw to get.

Rated 1 out of 5 by Disapointed in saw. Bought the MS 391 in March 2015. Used saw 4 times and every time about 1 hr. into cutting the saw stalls out and does not have power. I have to quickly pull throttle trigger multiple times to keep it from stalling or bogging down. I use 1 gallon of fresh premium gas and 2.6 fl. oz. of Stihl HP Ultra 2 cycle fully synthetic engine oil that I purchased with the saw. I took the saw back to the dealer (Hastings Ace Hardware) who I purchased it from and they removed the gas from the tank and placed it in a mason jar to observe it for several days. They showed a sample of gas to me and said the ethanol and gasoline was separating causing the saw to have the problems I am experiencing. I also did the mason jar test in my garage at home with the mix from my can and left over fuel in the saw's tank. Never have I seen any separation and the fuel looks uniform in color, nothing like what Ace Hardware employees showed me. The fuel is and looks fresh. Yet I still have problems with power and I am beginning to feel that I have a defective saw. I have a 2 year warranty on the saw, and I am just short of demanding a new saw or a return of my purchase amount in full. I also purchased a Stihl FS 56 RC string trimmer this spring. Unfortunately, I have not used the trimmer enough to know if I will have similar problems. I have owned another Stihl chainsaw for many years without any problems and this helped me decide to purchase other Stihl equipment. I cut an average 10 to 12 full chord of firewood annually and I really don't need mechanical issues with a new saw when I am in the woods. July 17, 2015
Rated 5 out of 5 by Lives up to the Stihl name This was my first Stihl that I purchased as brand new (got it while it was on sale). All of my other Stihls that I own I purchased as used (18, 28, 36, 44). It is just as reliable as all of the Stihls I have owned, with one exception: it doesn't run very well on old mix and it definitely needs Stihl mix to run at it's peak performance. My older Stihls were not finicky on old mix. For the price, this is a great saw for felling trees and crosscutting for firewood. July 11, 2015
Rated 2 out of 5 by Nice saw but pretty gutless. The saw seems to be well built but really has no power, which is unreal for the c.c. it has. It was that way from day one too. Its not like its old and worn out. use the saw around the house on small jobs and it struggles. Ive used lots of other saw of much lower quality that had way more power. I would not recommend this saw if you have any sizeable wotk to do. July 4, 2015
Rated 5 out of 5 by Great saw This saw is great. The power is amazing. It starts every time by the third pull of he rope. I will recommend that if you are experienced with a saw and cut a lot of firewood get a different chain. The chain that comes with it is a low kickback version that shouldn't even be put on a serious saw such as this. Morgantown Outdoor Power is an awesome retailer, very helpful. June 29, 2015
