Rated 1 out of 5 by Bad apple? What an absolute piece of junk. Do not buy. I repeat, do NOT buy this chainsaw! Problem after problem from day one. It's had a new cylinder and piston put in it, on top of every single warrantable part replaced. Along with a handful of non-warranty parts. Still doesn't run correctly. Much less, as advertised. Supposed to be a professional level saw yet you could walk into Walmart, buy the cheapest saw they have, and it would be more reliable. Extremely dissatisfied September 7, 2016

Rated 5 out of 5 by MS 660 1 year later After 1 year of use I can say the MS 660 is a great saw. Always starts on 1 or 2 pulls, never has needed the choke but you must use the decompression button. I have the 20, 25 and 36 inch bars with Stihl carbide chains, as I cut mostly flood damaged, dirty wood. I have not found a tree that even challenges the saw. After about 4 hours of cutting I may switch to my MS044 as I start to get tired. The MS 660 is heavy but that really does help when cutting a felled tree, just hold the saw and it cuts all by itself. I could not be happier with a chainsaw than I am with my MS660, although my MS044 and 009 rate real close. July 23, 2016

Rated 5 out of 5 by Power demon I added the ms 661 to my fleet this spring. I previously have owned a ms360, ms461, and a 201T, and an old 015L. The 661 I added mostly for milling, running a 36" bar with milling chains on an MK III mill. I have since put a 28" light weight bar on it, and love it. It walks through everything I have cut. Oak, hickory, walnut, nothing makes it bog. Twice after being shut down I could not get it to restart until it cooled off. I'm assuming it was an issue with the M-tronic while it was breaking in, as it has not happened for about five, or six gallons of fuel through it since. I always run super unleaded with the HP Ultra oil, since I had to rebuild the top end of my 360 after twelve years of cutting at least ten cords of wood a year on top of other work. I would say this is a great saw. I have no hesitation in making recommendations for this saw! July 20, 2016
Rated 5 out of 5 by Great saw I use my MS 661 with my Alaska chainsaw mill to turn timber into lumber on my remote property in Alaska. I make everything from 16' beams to wall studs and planks as thin as 3/4" thick. I use a 20" bar and ripping chain, man does this baby cut! Very fuel efficient and easy to handle. I have been using Sthyl products for over 30 years and have never been let down. July 12, 2016
Rated 5 out of 5 by Priceless I do full time selective harvest low impact logging. Broke in the 13th saw in collection. Bore cut a butt 60 inches wide. Went to the back and finished her off quickly..bucked off the log at 37 feet.35 inches at that height. Cut splits cracks or imperfections..thank you stihl..let's just say this is a good example of 26,000 reasons to buy a stihl!! Sincerely jack the veneer hunter..PS.,the wife made quick work of the limbs with a 441c.. March 27, 2016
Rated 5 out of 5 by AWESOME!! I bought this 661 after giving my dad my fairly new 441 this year. He had an old 028 and needed something bigger and I have an addiction to saws it seems.Recently my friend needed help taking down and bucking a few 24"-30" Beech trees and White Oaks. This saw fired right up and never stopped. Running my 362 with a 25", it sometimes bogs down, but not this hoss. I think ill keep an 18" on the 362 and run the 25" on the 661.I did not rate dependability, as i have not had it for long. I was hesitant with the Mtronic as I had an issue with the 441 when i first got it, but took it to my local dealer to recalibrate it. So far, i am 5 tanks in and this thing just keeps getting better.
