KM 91 R is rated 4.6 out of 5 by 15.
Rated 5 out of 5 by from Easy to start, fuel efficient, has a lot of power. I used my Stihl trimmer for the first time 04/10/2018. The unit started on the first pull. I have a brick fence around my yard which means there is a lot of timming to do, front and back side of the fence. The unit worked flawlessly and did not require refueling during the process. It does not bog down and did not require full throttle at any time during the operation. It is a fine piece of equipment. Best trimmer that I have ever owned. Cost a lot more than the ones I had in the past but looks like it is worth it.

Rated 5 out of 5 by from Work Horse So far I have cleared around 1500 feet of fence line, which includes 3' deep briar and small trees along with lots of brush. On the days I use this unit I average seven hours of usage time with a couple of breaks. I have several attachments for this unit, the brush cutter head, line trimmer and leaf blower. They are all work horses, the brush cutter head has a four blade grass blade and it mows through just about anything. Briar, thick grass, small sapling trees the diameter of a small finger. I have had the unit around two months now, it starts first pull every time. Make sure to read the starting instructions in the manual, this will ensure first pull start. The line trimmer handles the thick grass without a problem, and the leaf blower is better than a standard handheld blower. This unit is idea for any situation, I am impressed with the performance so far. One thing if you anticipate long periods of use, purchase the double shoulder harness.

Rated 5 out of 5 by from Great tool at a fair price for the quality. Just want you'd expect from a Stihl product. It fires up first pull, idles perfectly, and delivers plenty of power for the attachments that go with it. I've only used it a few times so far, but considering the money that used Stihl products go for I would expect a long service history. I will definitely be heading to the Stihl section when ready for another purchase.

Rated 5 out of 5 by from Great value for a versatile tool I bought this the other day after our winter storms in NH. Very impressed with its power and ability to usually start up with one pull. I also ended up buying the pole saw attachment along wth the graphite extension pole. Well worth every penny. I was able to cut down 6 inch braches 10ft in the air safely. Also, there is a promotion if you buy the mixing oil at the same time of purchase, your warranty is doubled. No brainer

Rated 5 out of 5 by from Best gas trimmer ever I’m happy with my Stihl KombiSystem KM90R I’m happy with its performance. Start easy every times, I bought more attachments and they work like champ. Especially the pole pruner, it cut 2” diameters like butter.

Rated 1 out of 5 by from This Product Won't Start This machine would not start when I went to use it. I took it back to the dealer who couldn't start it either. I told him I wanted a new one, he said there were no returns, and I said you better start it then or I am just leaving it here and calling AMEX to void the charge. He pulled the spark plug, pulled the handle a few times, replaced the plug, held the throttle down and pulled about a dozen times before it started. I took it home and it worked last week. I went to start it again today and the same thing happened except I pulled the spark plug, pulled the handle about 6 times replaced the spark plug and then held the throttle, pulled it a dozen times and it finally coughed to life. DO NOT BUY THIS. It won't start properly and they don't stand behind them with replacement.

Rated 5 out of 5 by from only used a couple times. So far so good. bought this for pole pruner HT-KM. need to get the extension for a little more reach. I already have a dedicated stihl weed wacker. It starts easy power good for what I need, home owner use. Will deffinetly get more attachments.
