Rated 2 out of 5 by from More time being repaired than used... I purchased this saw from a local dealer based on a recommendation after describing my needs/application. The saw worked great the first time used. Then the issues started...the saw is reliable and starts every time, but when I engage the chain and start cutting; the vibrations cause the top air filter/spark plug cover fall off. The saw has been into the dealer for repair twice now for this same issue. I just got it back and need to trim more branches off some trees on my property but am hesitant to use my saw. I highly DO NOT recommend this saw with the slide lock that keeps the cover on. I suggest looking at a model that has a more secure lock to keep the cover on. I asked the dealer if they would be willing to take this saw back due to it being defective and SELL me a more expensive saw where the cover locks, but was told that they couldn’t help me and that I needed to contact Stihl directly. What great customer service by the dealer!

Rated 1 out of 5 by from Used once. 2nd time it broke. Used it once and it worked fine. Stored without fuel. Used second time and piston broke. Was told improper fuel,but used gas mixed per stihl oil directions. Took to Ace and they said no oil in bottom of motor indicates improper fuel so not covered under warranty. I am not an engine expert so unable to validate diagnosis. Will not buy again.

Rated 5 out of 5 by from Great Saw! I bought my first Stihl (an MS 311) in early April 2017. LOVE IT. I picked up a 171 about 6 weeks ago for limbing and smaller jobs around our Northern MI vacation home. The 171 IS FANTASTIC. Like its big brother, it is reliable, powerful, very well made and I really reccomend it to anyone who needs a very good trouble free professionally engineered saw. I have used both quite a lot turning fallen trees into campfirewood and they are reliable, powerful, light, ergonomic, etc... Great tools!

Rated 5 out of 5 by from Great saw - very effective for larger trees than I thought possible I have happily used a still ms361 ( my "light saber ") and ms441 Magnum for years. But have begun back-country hiking and biking trail maintenance. So I bought this lighter MS171 saw to backpack ( in the often several mile hikes ) and clear trees down on the trails. Many reviews mention that this saw is for occasional use and small trees. But I have been surprised at how this saw will chew through 12 to 20 inch logs - even aged dead oak logs that are extremely hard wood. i am now happy to depend on this saw for all trail maintenance trees - unless a large tree "mess" dictates that I need to carry-in a larger heavier saw. As others have said, learn to sharpen the chain. It is small in width ; but that small width allows a small motor to drive through lots of wood. Keep extra fuel near, as the gas tank is much smaller than the pro saws. I use premium 100% gas with the new grey bottle stilh mix and have not had any problems starting. This is a great saw if one is patient and allows it to chew through wood at its own pace.

Rated 5 out of 5 by from Great Fathers Day Gift Got this saw for my Dad on Fathers Day. He loves how light it is, and how easy it is to start. He says the Anti-Vibration handle helps keep his elbows from hurting after a day in the tree line. -Phenomenal unit for the price!
