FS 40 C-E is rated 4.4 out of 5 by 243.
Rated 5 out of 5 by from Very powerful small trimmer. I've had this trimmer or actually the old version, fs45 for 4 years now and its still going strong. I've used it around my 1 acre lot and on heavy applications trimming high grass and weeds. Its surprisingly powerful and with the right line this trimmer is more than enough for most yards. If there is a downside, I would say it can be slightly difficult to start. More than 5 pulls.

Rated 5 out of 5 by from Great, dependable machine for the price I use this for my home on an acre lot. It works well and is easy to use. I am satisfied with this purchase and would again if I had to do it over again.

Rated 5 out of 5 by from Awesome product I did do research on the product. Sthil was rated well. It has done everything I needed it to do and more. A wounderful product.

Rated 3 out of 5 by from Always have had Stihl chainsaws and weed whackers but this is not one of my favorite. The trigger should be made of a different material with grooves or something so that it is not so slippery that your finger slides off or possibly more of a curve or different angle. It is somewhat top heavy and difficult to maintain a level trim.It does cut well but the manual is for several models and not clear on changing the string.

Rated 5 out of 5 by from Great trimmer for the average yard I recently went from a heavy duty professional grade Stihl trimmer to the FS-40 which is more appropriate for my yard size The trimmer is lightweight and has plenty of power for the average home lot.
Date published: 2016-10-17
Rated 5 out of 5 by from Easy to start and use. I had a battery powered trimmer that just wasn't cutting it. I went to consumer reports and saw where this model was highly rated and went to local store to check it out. After purchasing the trimmer works great and starts great. I know it is not a commercial model but my teenage son uses it also for some side jobs in neighborhood to trim with. Great product.

Rated 4 out of 5 by from So much better than the lower priced models Great for shorter people like me. It helps to keep the back straight so back pain is almost eliminated if there is a great deal of trimming to do. The only feature that might be improved is some sort of barrier to protect the right arm from the heat of the engine while holding down the throttle trigger lockout and the throttle trigger. Otherwise, it is well designed and easy to use.

Rated 3 out of 5 by from Worthless if you have to trim along fences and streets Having just bought this today I was excited to get to work with in in my yard. However it did not even come close to my expectations. Motor is plenty strong, easy to start but that is all I can say for it. the following are the issues.1. Head design is horrible - line is 2" above the bottom of the head and you have to tilt it so far over that the line angle starts to gouge your yard.2. Max line size is ok for grass but going up against fences or down a curb you have to bump the line every 3 feet because it is so flimsy.3.Upgraded to the self winding line head and that is a joke! Unless you are a gorilla it is very hard to wind.Could not even finish the yard with it because it was so bad.
