Rated 5 out of 5 by Best trimmer I've ever used The FS100RX is the most well rounded trimmer I have ever used. It has a balance between being light weight and very powerful. For this particular machine I have noticed two things about its characteristics in that respect- the power is easily controllable and it has substantial advantage when it comes to torque. In my experience as a professional landscaper, I have learned that having that torque is a life saver when it comes to thick or wet grass or weeds. Another characteristic of this machine that I've noticed is that it is very reliable and has a very stout, robust feel to it. I could go on for several paragraphs about this trimmer's strengths, but there is not a single weakness or drawback that comes to mind. However, they are capable of throwing grape-sized pieces of debris across considerable distances with ease. Outstanding product overall. March 26, 2016
Rated 5 out of 5 by Lightweight with plenty of power I have bought three of these trimmers and seem to get 2 years of commercial use out of them before any adjustments are needed. March 18, 2016
Rated 5 out of 5 by The best dedicated trimmer. We exclusively use the FS100RX for edging/trimming due to its lightweight and maneuverability. Going back to an FS90 or 110 just felt bulky. We have 8 100Rx's and will keep buying as long as they are made. February 10, 2016
Rated 4 out of 5 by yes but no, I would recommend this to product any one that has a normal pace. Not powerful enough for me. I have a fast pace so the trimmer can't keep up with me that is why I have the con. Other than my experience this machine is a work horse. It never breaks down, never is hard to start, fuel efficient, and very light weight. All in all I would not buy because of the speed I use it at. If I wasn't so tall with long legs I would buy this.

Rated 5 out of 5 by Beast This weedeater is a beast. It is light for the power it has. I have always run Echo weedeaters so this was my first Stihl. It will not be my last. I still run Echo equipment but this Stihl weedeater is the lightest for the amount of power and torque it has. September 17, 2015
Rated 5 out of 5 by Great Trimmer but a pricey FS 100 RX The 100 RX is lighter than the 90 I tried and more powerful and only $25 bucks more !! It gets a little hot on the arm if your resting it against the trimmer's motor as you work, but that's a bad habit I have. Very powerful, easy to start. A little pricey but dependability is what counts. Nothing worse than having to fiddle with equipment when your trying to get something done. Use only non-ethanol fuel with your oil mix !!! I run premium with no ethanol fuel with great success. July 14, 2015
Rated 5 out of 5 by our new standard We were always intrigued about these trimmers but we didn't need any until they stole our other trimmers. And the sweet out of this bittersweet story is this specific tool. Our commercial business demands powerful, lightweight, and dependable tools like this. We decided to try this trimmer since we love all of our other Stihl products and we needed to replace the stolen ones. I'm glad we opted for this tool. It is lighter and more powerful then what we were used to. So now this will be our new go-to string trimmer. Nothing less. May 1, 2015
