Rated 5 out of 5 by This thing is a beast!!!! Wow. This thing is a beast. It cuts through the toughest of grass with ease. Very balanced and no vibration at all July 20, 2015
Rated 5 out of 5 by great product i mow about 10 yards and this weedeater has plenty of power and I think that it is well worth the money. I have had this weedeater for going on 3 mounths and I haven't had to choke it or prime it. it will start first pull every time and I am very pleased with this weedeater. July 14, 2015
Rated 5 out of 5 by VALUE PACKED ADAPTABILTY I purchased this unit from McKinney Power in Ruston, LA. It was replacing a 12 year old unit that had been used commercially and privately. The staff really saved me time and money by showing me buddled specials also from STIHL. There's so many interchangeable pieces that cut down on storage and costs, you can't go wrong. There's no doubt about it, STIHL makes the most dependable and toughest units on the market. Don't waste your money on cheeper products, you'll only spend more replacing it year after year!

Rated 5 out of 5 by Great product! If a weed eater has ever found an occupation to test its durability; it has found one with us in accompanying our land surveyors in the mountainous region of Western North Carolina. We use our stihl to cut everything from tough 4" hardwood vegetation to the grass at the bosses house. The last thing we want is to hike in for an hour at the job site, just to find that the weed eater does not start, I am happy to say that has never been a problem with our FS 90 R. The power is sufficient to run the chainsaw attachment effectively and with the blade attachment it powers through brush with minimal effort . July 10, 2015
Rated 5 out of 5 by Reliable!! Easy starting! Light weight! This is just an overall good product! Would recommend it to anyone! Love it! July 8, 2015
Rated 5 out of 5 by best trimmer i have ever used i use this trimmer every week and has never let me down it will always start the first or second pull July 8, 2015
Rated 5 out of 5 by Best Trimmer Ever! It's a Stihl of course I have been working in the Lawn Care and Landscape industry since I was 14 years old. I am now 25. I have seen everything and used just about every weed trimmer out there.The FS 90 R is by far my favorite. I first used this model in 2013 at a big cemetery in Mustang, Oklahoma. I was able to complete the whole job without taking a break (about 5 hours of weed eating). Also, I only used roughly a tank and half of fuel.Before I used this trimmer my favorite was the FS 110 RX. Although it has plenty of power, it weighed a lot compared to the FS 90 R. At that same cemetery I had to take at least two breaks, and used a little more then two tanks of fuel. It took me about 6 hours to complete the job with the FS 110 RX.So I saved a little more than a half tank of fuel, and an hour of time. In the Lawn Care and Landscape industry "Time is Money."Of course, if you know Stihl, all the products they produce are very dependable (in my opinion, no other manufacturer comes close).I also have a 1995 model Stihl FS 44 Weed Trimmer. It runs like new and has plenty of power as well. It has been very well cared for and handed down to me by a family friend when he passed. If that isn't proof that Stihl products are dependable then I don't know what is.If you want a product that will save you time and money that will never let you down, then look no further.Thank you Stihl for giving the customer what they need.
