Rated 4 out of 5 by from Light and easy to handle in thick brush Small and light but just enough power to get the job done! It was easy to carry through the woods cutting out shooting lanes. It easily cut through saplings and six inch pines. Just remember to keep the rpm's wide open

Rated 5 out of 5 by from Great small job chainsaw, dependable. I've had this saw for 2 weeks, had to do some major storm cleanup. 15 trees down some of them up to 14" wide. The saw cut through everything with ease. It is a little under powered at times but that is expected with a small chainsaw. I was going to get the MS80 but they were sold out and I needed something. Easy to start every time, even when there was snow on the ground.

Rated 5 out of 5 by from great saw I have an ms251 that i love, but is heavy to use overhead. so i wanted a smaller, lighter saw. i picked up the ms 171 and love it. it is easy to start, runs fantastic and you can use it over your head with no problems. I have even sunk it into some very large logs and it just cuts. very nice saw.

Rated 4 out of 5 by from Looks good, used to start easily. After only 8 months of minimal use it wouldn't rev up. I used this saw occasionally but after only owning it for 7 months I had to put it in the shop. Turns out the carb was shot and needed to be replaced.

Rated 5 out of 5 by from good saw good product, easy to use and service. What the buck, buy one cut down some trees and take care of it. Will last for years.
Date published: 2018-04-18
Rated 4 out of 5 by from Great for a budget I got this saw cause I couldn't afford a bigger one. Works great, a little small for what I'm using it for, but it gets the job done with a little patience.
Date published: 2018-04-17
Rated 5 out of 5 by from Great saw! Reliable, easy to use and fair price. Love the saw. I have 10 acres in Mosier, OR with lots of Ponderosa Pines. Unfortunately beatles have killed many trees that need to be cut down and burned. I use a large saw to cut down the big trees and my small one to cut up all the branches. This small saw is easy to maneuver amongst the branches!
