Rated 5 out of 5 by from Great trimmer No string problems works great. I did buy the larger shield.

Rated 4 out of 5 by from Trims nice, but buy a face shield Replaced a 20 year old FS36 with a new kombi system power head and the FS-KM trimmer. This is a nice replacement set up. Starts much easier, not as loud, and a larger gas tank.I have not had any of the string problems mentioned by others here after re-wraping the string on the head cleaner then how it came from the dealer.My only dislike is with the very small string shield, grass, sand, and small pebbles fly everywhere including up into your face. I suggest if you do not already own one purchase a face mask right away if you purchase this head. I have always used safety glasses and hearing protection in the past, that is not sufficient for this model.

Rated 1 out of 5 by from Line Issues I purchased this head trimmer attachment for my kombi system and am having the same line issues as everyone else. The line constantly breaks off inside the head. I see Stihl responding with the same "soak your line in water" response to everyone. What I dont understand is why Stihl isn't doing anything about the actual issue? I've never had to soak a competitor's line in water, ever. Maybe Stihl should think about sourcing their trimmer line from a different supplier, and replace those of us who purchased the faulty line with higher quality line. This attachment will be sitting in the shed if i have to constantly stop and re-line the trimmer.

Rated 5 out of 5 by from Excellent attachment paired with KM130 Prior to purchasing this Kombi System I had purchased a similar system from A competitor years ago and was left underwhelmed and firm believer in purchasing each tool for specific task. Nick, Harris Ace Hardware's (Hinesville, GA) Stihl mechanic/ sales, coupled with reviews online and price savings vs purchasing each tool separately after shop was burglarized and equipment stolen swayed me to try this line. I purchased each attachment from pole saw, brush cutter, blower, trimmer and straight edger and have been blown away by the power and versatility of the entire system. I have read all the reviews of the line breaking and have to attribute this to user error as I have not had one issue from this head even when flipping it to edge sidewalks, beds and curbs which will quickly run through the best string. If you have prior knowledge of the button and correctly spool the string then you should rarely encounter any line breaking within the head. The deflector was adequate for me in rocky soil and thick weeds. The power can be to much for some applications and have to feather it to about 3/4 or else a spool of string can be deceimated quickly. All of the other attachments are also top notch and the only complaint is the balance of the system but benefits far outweigh any negatives.

Rated 4 out of 5 by from Line cutting in the spool issues Ok, great product. However, you have to know how to properly put the line in this or you are doomed to failure. I was in fact doomed to failure because I didn't know the tricks. I watched the dealer guy spool the line in, He did it evenly and once he was done, he put the spool in, fastened the cover back on, then he pulled on both lines, then "click". Bamm good to go. That was literally the only thing I was missing and that made an absolute world of difference.

Rated 2 out of 5 by from The head stinks Used the trimmer for the first time today about 20 min total run time. During that 20 minutes the line broke off inside the head 3 times. It's a major inconvenience to stop what your doing and rewind the string constantly. The deflector is a joke buy the large deflector and toss the little piece of junk in the trash before you leave the dealer.

Rated 5 out of 5 by from Satisfied overall Trimmer head is just ok. I have not tried soaking the line though. Sometimes breaks off line completely. Not a quick fix. Question; Is the trimmer head the same on the FS 90R as my KM90R?

Rated 2 out of 5 by from Constant problems with trimmer line heads Without exaggeration I've spent more time messing with the trimmer head than I've spent using this attachment. The first 1/2 hour of use was good, the line fed as it should, then the problems started and never stopped.The problem is the trimmer line breaks off in the head and when it doesn't do that it ties itself up in the head. I've bought new line, and re-wound the spools, and had the same issues. I've bought a second head, and re-wound it. The problems started with heads and line out of the box from the manufacturer, so it's not operator error.The trimmer works adequately when it works...which has been about ten minutes tops until there is a line problem. I love the Kombi idea, the trimmer attachment attaches quickly, the power head is great, but the line heads are ridiculously fussy and should not require so much attention.
