Rated 5 out of 5 by from Best Saw. This is the best saw I have ever owned. I have owned Poulan, Homelite before and they didn't hold up to the work.

Rated 1 out of 5 by from The 171 I purchased is not very good, Len's Ace Hardware is worse. Difficult to start. Takes a while to warmup. Purchased from Len's and their return policy is very poor for power equipment. You may not return the product once you put gas and/or oil in the product. They actually put in both to start the product in the store. The young man doing this had a hard time starting the machine. Once I used the product I had a hard time starting the machine too and took a few starts to stay started. Went to exchange the product for the 180 model (my poor product is the 171), they would not. DO NOT PURCHASE FROM LEN'S ACE HARDWARD for this reason. Owned a 180 before and was very happy with that, this 171 is not very good at all.

Rated 5 out of 5 by from Best ever! I don't use a chain saw very often. But when I do I want it to work. My last one let me down too many times (brand omitted because I won't call it by its proper name) I bought this saw and it started right up and worked great. I used it a couple weekends in a row and I wore out before it ever slowed down! I'm looking at buying Stihl for all my power tools from now on. The guy that waited on me at Aker's Hardware was very knowledgeable about the saw too. It's been a great experience.

Date published: 2017-04-06
Rated 4 out of 5 by from I like it so far! So far, so good, Easy to start and capable of trees up to 12", but it's a little tough on this little beaver, so best uses are limbing, smalller trees,etc. Lighter than my older H-44, but don't know if that is a fair comparison since a lot more plastic is used in late model saws? Hope it holds up for the long term...

Rated 4 out of 5 by from Light saw, steady workhorse Light saw for all day cutting! Perfect for the weekend homeowner who isn't going professional. Not a power-hungry saw but keep the blade sharp and let it do its job and it does great. Great for dropping small 8" trees, limbing, and use as a tool. Anything bigger, get a 311. Always easy to start. Easy to clean and maintains. Buy this before ANY saw at Lowes, even the bigger ones. Never a fuss or too much work to maintain. Stihl: always reliability, rugged and built by great people who know who their building the saws for!
