FS 111 RX is rated 3.5 out of 5 by 21.
Rated 4 out of 5 by from Made for heavy work Had to change my weed eating tactics. Keep it loaded up when cutting to prevent rev limiter from kickin in. This ones to big to trim edges but will make quick work on an open field of weeds. My new FS 111 RX uses much less string than my old fs 76 stihl. I've owned it for 3 months.

Rated 2 out of 5 by from You will be replacing the ignition coil after a year 100% of these trimmers I’ve owned have had an ignition coil go out in them after 1 year. I use mine commercially 3 times a week. I bought 2 of these last year and now I’m having to replace the coil in both of them. They do offer a two year warranty so the work was free but having a machine down for warranty work for 2 weeks isn’t exactly what you want. The good thing about these machines is they are light very powerful and start up every time with no hassle if they would figure out the ignition coil and get that fixed I would give this weedeater 5 stars.

Rated 5 out of 5 by from Powerful engine, easy to start I bought the FS 111RX after moving to a larger property, where my old machine simply wasn't cutting it anymore. I have only had it a few weeks yet, but it starts easily, runs well, and cuts great! I am confident that it will continue to work well, as all my other Stihl products have. (I have also received good support from the company, which is more important to me than the initial product performance!) I have a 1,000 linear foot wire fence (and have to trim both sides of it) that is very tough on string, and already had to re-wind the stock bump feed head. I may replace the head with an easier change version at some point, but for now so far so good. Thanks for another great product, I look forward to many years of service from this machine!

Rated 1 out of 5 by from Difficult or won’t start I bought this weed eater approximately 1year ago. Have got it to run maybe 4 times since buying it. In addition I have also bought 2 more since because it is not dependable with starting. Would not recommend this product

Rated 1 out of 5 by from THIS REVIEW IS FOR STIHL TO READ Have been using for Stihl for 18 year for my lawn care Co. I have always been a big big fan. But what the hel happened with this FS111 RX? The new design is not user friendly at all. You need very small fingers to able choke it. And not posable to choke it with gloves on. The gas trigger is very short and can only use one finger. This makes it hard to use for long Hrs. This trimmer is not smooth like the fs100 rx and is not balanced. Very jumpy and to me feels like I'm trying to lean how to trim all over again. I never leave reviews for anything but somebody need to hear about this one. Stihl YOU DROPPED THE BALL ON FX 111 RX.

Rated 5 out of 5 by from Amazing machine This is the second stihl product I have purchased the first being the br700 back pack blower....but I have owned 2 older stihl products that I was given by my grandfather who bought them new 20+ years ago...both old blower and trimmer still work but were just tired and Ive now got over 4 acres of lawn to maintain so needed some new stuff to be able to make my job easier...I have over 900 feet of fence to maintain and that's not including the house barn and pond and the fs 111 rx makes life so much easier than my older stihl....takes me half the time with the fs 111 rx ....this thing eats the grass like nobody's business ....uses less gas and LES string as well...I've always been a fan of stihl products but these new ones are hands down the best I've ever used...yes they aren't cheap but I believe you get what you pay for and stihl products are by far worth every penny especially if they last as long as my hand me down ones I received from my grandfather...20+ years and stihl going lol...keep up the great work and the great products

Rated 1 out of 5 by from Runs Rough The FS 110 RX was a much better model. It ran smoother, started quicker, and handled more comfortably.
