FS 111 is rated 4.3 out of 5 by 15.
Rated 5 out of 5 by from Beyond expectations Having used the same Trimmer/brush cutter for twenty five years (and it still runs), I was hesitant to buy a new one. My wife bought this for our Anniversary. I am amazed at how easy it starts, how quiet it is, and that it is a four cycle engine that uses two stroke gas/oil mix. What a feat of engineering. This unit came with the cup,washer and nut to hold my brush blade which has only four chainsaw cutters. I was again amazed at the power it has to cut through limbs and small trees at very low throttle. For the Stihl Autocut mowing head, I replaced the round profile line with cross profile line as that is what I've always used, and mowed through some tall field grass. Again amazed at how efficient it operated at very little throttle and it's abundant power. This is a very welcome addition to my 15 year old O36 Stihl Chainsaw and will most likely last the remainder of my days.

Rated 3 out of 5 by from Nice easy starting so pull gently! This is a Cadillac weed trimmer. Very low vibration and starts easy. Negative is the handlebar does NOT stay in place. The constant low vibration still plays a part in the handlebar sliding down towards the ground. The bar is made from aluminium and it is secured by cast aluminum with no knolling. I have inserted a piece of friction tape but that only slows the issue down, not remedy it. Next, I will contact Stihl for their say.

Rated 3 out of 5 by from Good Brush Cutter, Terrible Trimmer I bought this at a Big R store in Monument CO. The dealer service was great but I almost took the machine back because the string trimmer is so terrible. I tried lighter string as well as the heavier string and neither will feed well. If you are cutting anything other than sparse grass you have to slam the trimmer into the ground every 4 or 5 feet to keep the string out. However, that often doesn't work and one or both sides of the string will break off inside the spool. Don't even think about trimming up against a solid surface. The only thing that saved this sale was that the brush cutter blade does a good job of removing small scrub oak saplings and I have a lot of those to remove. Perhaps one of the alternative trimmer heads will prove useful but the one that comes on the machine is as sorry as the ones on big box store units.

Rated 5 out of 5 by from show these 111's more love people it's light weight with decent power got it last wednesday and it gave me a good first impression startin on the second pull im currently on its 6th tank of gas and so far it's continued to start easy and seems to have decent power and it'll run any blade real good with plenty of power to run em while more powerful than my 91R but not as powerful as my 130R and both of my 131's i think it's gonna have enough power to do just about anything ive still got a little more testing to do but like the 91R and my other machines i think it's gonna be a good decent machine for anybody and it's lightweight too so a person wont get too overly tired runnin it and yeah i do recommend it for anybody lookin to buy this model or one of the other 111's

Rated 5 out of 5 by from A little under powered but overall good I bought this as a crossover product. I needed a brush cutter and weed wacker so this was my happy medium. I'm mostly brush cutting hardwood beech saplings and as long as I keep the rpm's up, it's fine. It just takes a little to get it up to speed. If I were to do it over again, I would buy a lighter weight weed wacker and full on brush cutter. My fault for trying to do both with one. It feels heavy when you pick it up but once the shoulder harness is on, it's very well balanced. I use the weight to my advantage when cutting brush. It has a very solid feel. Start up is simple but keep in mind, it's a four stroke so if it's colder out, you'll need a 30 second or so warm up. By the time it's started, I put on my helmet and gloves, then strap it on and go. I don't regret the purchase and am satisfied. Great quality product.

Rated 2 out of 5 by from not the best I have used stihl products for years. This is my first disappointment. Trimmer has no power, looses power any time you get into thicker grass. Has wicked vibration. Now has a paper air filter which isn't goin to work in the Florida rains. Also has a new trigger which is going to break. Previously has the FS100rx, loved the product. This new model is not going to work for me.
