Rated 5 out of 5 by from This product is as advertised. This product has a lot of power, but more important is that it starts every time. I have no idea why I waited so long to buy this trimmer.

Rated 2 out of 5 by from Won't stay at high throttle I love stihl so don't think I'm writing this to down on stihl. It's just I have recently bought the brand new fs91r and since day one the weed eater would not stay at high throttle when string extended. And I took it in for repair 3 times before someone found the filter was dark brown. Said it was from ethonal in gas and that I got the bottom of the tank. He said to only use 93 or ethonal free gas. Well seeing as ethonal is not at every gas station I have done 93 and now it's doing it again where it don't want to run when string is out. But the past three weeks after it has ran awesome. But now having same issue as before. Still not as good as my old fs90r I had though.

Rated 4 out of 5 by from Very good product. This trimmer is the best you purchase for your money. It is professional grade, so if you buy it for your personal yard use it is the last one you will ever have to buy. It zips right on through tall grass and weeds with ease. I bought it because I got tired of the home depot grade and i wanted something that will last for long time and I have no doubt that it will. It starts up with no problems and once it warms up its ready to get the job done. I am very pleased with this investment and the price wasn't to high. I recommend this particular weed trimmer if you need something for your home use and you want it to last,

Rated 4 out of 5 by from Ready for a good day's work. After wearing out an older string trimmer with handlebars, which I liked, my Stihl dealer sold me on a 91-R, which I have used in getting ready for this summer's fire season. The extra volume in the fuel tank has made my work in trail clearing and a clear zone around the house a lot more efficient. I can get through a whole day with just a couple of pauses to re-fuel.It took me a little-head-scratching to figure out a tiny little change in the way the head opened up to replace the trimmer line, and I needed to whack the ground a little harder to make the bump-feed work, but in the end, it was only a bit different from the one I was used to.Overall, a good piece of equipment.

Rated 5 out of 5 by from Awesome machine This by far is the best trimmer i have ever owned. I trim over 300yds if ditches and around 2 acres. No bogging down and no mercy. Perfectly balanced. I love it!

Rated 5 out of 5 by from Worth it! I just bought the FS 91R to replace my old trimmer that had become completely unreliable. What a difference! I've only used it once so far, but it runs so quietly and has so much more power, that I didn't even mind the work as much as I normally do. The machine started right away and is very easy to handle. I'm a woman maintaining a small farm and this will absolutely make my life easier. I do plan to get some heavier line as the line that came with the trimmer breaks too easily with some of the heavier weeds, but I'm quite pleased with my purchase thus far. This is my second Stihl product (I also have a chainsaw), and I'll definitely recommend and purchase more products from this company. You do get what you pay for!
