FS-KM Line Head Trimmer is rated 3.6 out of 5 by 42.
Rated 2 out of 5 by from Motor runs great, but feeder head needs work. I own a lawn service and wanted a quality tool, so naturally I purchased a Stihl. I purchased the KM 131 power head, the bed edger, the string trimmer, and the BR700. I expected a quality feeder head like the other components. Within one minute of beginning to use the trimmer for the first time, the line broke at the out feed location. I spent more time taking the head apart multiple times at my first customer, than using the trimmer. Not only is it hard to take apart and restring, it's a pain to do. What I don't understand is why they didn't put a speed loader on a commercial unit knowing time is money to us commercial mowers. I've read the review saying to soak the line. I've never had to soak line for any string trimmer I've purchased. Never had this issue with any other string trimmer.

Rated 5 out of 5 by from FS-KM line head trimmer I purchased this trimmer with the KM 94R power head and the HT-KM pole trimmer. I have had this Kombi combination long enough to know that this trimmer is the best trimmer that I’ve used. I find it is easy to replace string in the field, no tools needed. I have used several different replacement strings without any problems with feed. The 94R has more than enough power for this attachment, although it is heavier than a dedicated trimmer. I have not had an issue with either piece in the eight years that I’ve owned them.

Rated 2 out of 5 by from Initial review after using the km91 head with the line trimmer After about 5min of use both lines broke with the line supplied with the unit when purchased. I didn't see any instrcutions but after looking at the trimmer head was able to dissamble the unit and re-thread the line. Both lines broke again within 5min. RE-streaded the line again. This time I tried to advance the line regularly. The trimmer line will break quickly and force you to fix it if you are cutting along any sort of fence/stone/hard edge and let the trimmer get within a couple of inchs. I found if I stayed farther away from things it was less likely to force me to stop and fix it. I had the lines break maybe 5 times for I was able to run the unit long enough to use up the spool. Reloading was easy enough if you read the bottom of the trimmer head spool as it is labeled with instructions to wind the line.I also have a 660cm chain saw which I love and a 56 hedge trimmer which I start up and just trim things because frankly it is fun to use....the trimmer is not so much fun at this point, I am a little disappointed with it to be honest.

Rated 5 out of 5 by from It just works. After having several trimmers over the years and using others at various points in my life, I can honestly say this one is the best. From batter powered, to gas powered, nothing beats this trimmer. Using ONLY STIHL trimmer line, it has always conquered any job I have given it and even though the winding of the trimmer line can get a bit annoying, its far and away worth it to have it simply dominate anything I can put in front of it.

Rated 1 out of 5 by from Autocut 25-2 This has to be the worst auto line feeder head I have ever used. I have yet to go through a full load without having a misfeed on one or both lines. Currently looking for a replacement head.

Rated 5 out of 5 by from Great Alternative to Multiple Tools This was the first attachment that I bought with my KM90R. I'm a residential homeowner and I use it semi-frequently (a few times a month). It's easy to store, easy to wind line, and the head is strong and stout enough to handle .095 line to cut through the thick stuff.

Rated 4 out of 5 by from Almost perfect but has one caveat I purchased this in combination with a 111 power head. It's a great combination. The 111 drives this thing perfectly. I replaced a homeowner type gas trimmmer with this and have also used home owner Stihl trimmers and a couple professional dedicated trimmers. Comparatively speaking this thing is a beast. I usually run it along my edged beds in a verticle position to quasi-edge my lawn. It works well for this. I did notice on the first day that the trimmer line does often break off right by the head. That was a pain for the first 15 minutes. Others have complained about the same issue. I then started refreshing the string (tapping it and letting out more line) more frequently, keeping the line length longer. This solved the issue completely. Now it's a pleasure to use. Replacing the string is fairly easy compared to my old big box store trimmer.... and it holds a lot more. I use this addition to a bunch of other Kombi attachments. Overall the Kombi system is a fantastic system. Highly recommend. I hope this review was helpful!
