Rated 3 out of 5 by balance / throttle response Long time user of the other brand. My first new Stihl trimmer is a little disappointing. Throttle response from idle is not smooth and incremental. It jumps to a high rpm. Even with a feather squeeze. Holding it sideways to do the edging of a sidewalk or curb, the engine head is not balanced and wants to over rotate. So now not only do you have to balance it sideways but also have exert a little more muscle to counter the weight of engine head from turning the trimmer upside down. April 22, 2015
Rated 1 out of 5 by New trimmer already does't start Purchased the FS 90 last fall and used maybe 5 times residential use. Drained tank and carburetor when stored over winter. Filled with fresh gas and Stihl oil and will not start. Took to dealer and they said it was not covered under warranty and needs a new carburetor. Price for repair is almost as much as I paid for trimmer. First and last time I ever buy a Stihl unless customer service handles this. the whole reason I bought this trimmer was the 2 year warranty. Will update when I hear back from them. Already three weeks into cutting season and no trimmer. April 22, 2015
Rated 5 out of 5 by Money well spent I bought this trimmer last year (2014) and it was the best decision ever. I use this around my house and on the properties that I cut. Starts up every time I need it, battles through the toughest and thickest weeds. I would recommend this to anyone who is looking to purchase a trimmer. When I bought it, I a 2 year extension on my warranty by buying the oil to mix with gas. The line that comes with it is ok, but I used it all up until I changed with with the green line.

Rated 5 out of 5 by Love this trimmer! I got a Stihl because my Dad got a Stihl back in 1986, when I was a kid, a uses it to this day! I have owned my FX 90R for 4 years now. I have a lot of concrete to trim around and use my trimmer every week during the mowing season. 99% of the time it cranks cold on the first pull. For the past 3 springs it has cranked on the first pull on the first use of the year. The only con I have with it, being a 4 stroke you don't get the same throttle response you get with a 2 stroke. I have learned to work around it but, I would love to see it improve. Other than that I love my trimmer! April 10, 2015
Rated 5 out of 5 by Great piece of gear I purchased this Stihl FS 90 R about 4 days ago and I'm truly impressed with the results. I will never purchase any other brand but Stihl. April 7, 2015
Rated 2 out of 5 by I regret buying it. Was looking forward to owning a dependable weed eater, at least according to my friends. that was wrong... I bought this trimmer in Feb. 2014 and hardely used it. Its a bit timmed to start and the bad thing about the trimmer is the string feed does not work properly. I have taken the string all out and replaced it with fresh string thinking it set on the shelf to long, and no change. I weed eat my yard the other day and took the head apart 4 times to refeed the string. This is not good. March 17, 2015
Rated 5 out of 5 by This trimmer is the real deal. This tool is a real weed and grass guzzler that can tear and rip through anything that nature has to throw at it. The durability and power on this trimmer is unbelievable and truly stands above the rest. Best tool ever made from this company. Thank you Sthil. March 3, 2015
