Rated 5 out of 5 by Very good trimmer for shorter people. This was my first stihl string trimmer and I love it. It has everything just right for someone who hasn't used a string trimmer before and for someone who is used to curved shaft string trimmers. April 30, 2016
Rated 5 out of 5 by Great company and great product Have owned Stihl's trimmers, blowers and chain saws for over 20 years. Finally wore out my FS 45C trimmer and purchased a FS 40 replacement and it works just as well if not better. Great products and very reasonable prices. Too bad Stihl doesn't make a car.....

Rated 1 out of 5 by Questionable Quality The trimmer was always a little hard to start. It never idled smoothly, and if it died when in use it was very hard to start. It then run when started but immediately died. I did all the recommendations on exhaust screen, fresh gas, new spark plug and air cleaner. Finally I took the carburetor apart and found a small oval plug dislocated and moving around it's chamber. There was also a clear rubbery substance in the same chamber. I replaced the oval plug and staked it in place. The trimmer ran like new, but when put away the cylinder now fills with fuel and blows out the exhaust when trying to start again. I think the clear rubbery substance was the seal under the oval plug which now leaks fuel into the cylinder when not running. All I can say is I found poor quality parts with the carburetor and it undoubtedly needs a new one. Not sure I want to continue to fool with this product. April 22, 2016
Rated 5 out of 5 by Does The Job Required and Then Some Good size and very powerful. Cuts the grass, the overgrowth and then some . Was very surprised and never bogged down at all.I like the curve shaft because it give more "in" control. It is comfortable and fairly light. I have cut all day with no trouble in my yard that had much overgrowth and some narrow areas.It will be easy to maintain but you must follow the instructions carefully and everything is easy after that. I learned the hard way, but after following the instructions (sometimes not very clear) it worked fine and was no longer bothering me.Fuel bulb a bit stiff to push but a really minor thing.

Rated 4 out of 5 by Powerful yet light weight Decided to find a lighter weight trimmer for the yard work. The FS40 is just that plus more. Light weight, powerful and easy to start. For me, trimming takes about 30 to 40 minutes. I can assure you this trimmer makes short work of that while not putting a hurting on my arms or shoulders as its so dang light weight. The tap and go line system is a must. The idea of the trimmer being built in the USA with a great warranty pretty much sealed the deal on buying from Stihl. Well worth the investment. April 15, 2016
Rated 2 out of 5 by Runs great Runs great; starts easy; plenty of power.All the available trimmer heads are garbage; too bad, because otherwise it is good; my advice spend a little more and get ome that accepts attachments. April 4, 2016

Rated 5 out of 5 by Going Strong After 6 Years I've owned this model for over 6 years and am completely satisfied. Easy starting is the best thing I can say. Never takes any more than 3 or 3 pulls to start. September 27, 2015
