MS 171 is rated 4.2 out of 5 by 123.
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!

Rated 1 out of 5 by from Garbage straight from the dealer I was having a fence put in and needed to cut down 2 small trees.The dealer told me it was all serviced and ready for use out the door. The chain was binding on the very first cut, this thing couldn't make it through 6 inches of wood. I tried to adjust the tension but the tension screw was already stripped, the chain was hanging off the blade and couldn't be tightened any farther.I will never buy Stihl again, my leaf blower is ok but this thing is unforgivable.
