MS 171 is rated 4.4 out of 5 by 96.
Rated 5 out of 5 by from Ms171 Good little saw. Used it all day no problems. Starts real easy and has plenty of power for its size. Real glad I made this decision to buy this saw. I put 0.50 bar and chain on it and makes a big difference in how it cuts too. Happy trimming.

Rated 4 out of 5 by from tough little saw that hits its niche well We were clearing nearly an acre of forest that was far too close to the house. I bought this as my first chainsaw, since my brothers-in-law were doing the main clearing work with their massive saws, but I needed to clean up debris and cut up the wood (that wasn't going to the mill as logs) for firewood.This little saw "saw" far more use than I'd have thought when I bought it. I've also used it to tackle some firewood rounds that were about 20" in diameter (yeah, it's not best suited for that and tends to bog down, but eventually it chewed through). In hindsight, a larger saw would've been nice, but I'll not regret purchasing the 171. For delimbing the trees after they are felled, this thing is perfect. It's so lightweight that you don't get tired from holding the saw at the weird angles you need for delimbing. I also found it perfect for chewing through the dense underbrush that had grown up around the house. I used it to take down some small 6-8" diameter trees with no problem, and it works well for firewood rounds 14" and smaller.

Rated 5 out of 5 by from Good product Great motor and handling but the chain that comes with it isn't worth the metal it's made of. Cut half a cord of wood so far and blade is full. I guess that is normal I was just hoping it would last longer before it needed attention.

Rated 5 out of 5 by from Love this saw I use this saw at work . Had to buy one for home. Great saw for the money.

Rated 5 out of 5 by from Easy starting; runs great! This saw starts very easily, normally on first pull (after initial cold start - and even the cold start is easier than previous saws I have used). My previous saw (not Stihl) started good cold, but was a real pain to start after it was hot and had been left a few minutes.Highly recommend this saw to anyone that wants to "saw" as opposed to "crank".

Rated 5 out of 5 by from Stilhl Crazy This saw starts easily, runs smoothly, and cuts quickly. Easy, smooth, and quick are three good adjectives to describe this chainsaw. A-1 Rental in Sand Springs, OK did a great job of setting up and registering my saw. I am pleased.
