Rated 5 out of 5 by 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? September 12, 2016
Rated 2 out of 5 by 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. September 12, 2016
Rated 2 out of 5 by Suppose to be the best Doesn't seem to be running right. dealer says it's O.K. Sputters at full throttle. September 7, 2016
Rated 3 out of 5 by Great Kombi tool, but..... This is another great Kombi attachment! However, the bump and feed trimmer head is no better than any other out there. I was hoping it would perform better than those I've owned in the past but not so. I spent more time fishing broken line out of the head and rewinding the line than I did trimming! I finally bought the Durocut head and installed it. WHAT A DIFFERENCE!! I would recommend doing the same when you puchase this attachment. It will save you a lot of frustration! June 14, 2016
Rated 5 out of 5 by Good trimmer attachment, same issues with head as others. The trimmer itself is fine. I do have the same issues other have talked about with the auto dispensing head though. Sometimes I lose the line completely and have to pop the cap off and refeed it. A bit of a pain.But, I have worked with other trimmers and it has the same issues. April 25, 2016
Rated 5 out of 5 by 20 Years Strong I guess after 20 years, I can say it's good product! Bought with KM 55 powerhead based on recommendation of Reynolds Farm Machinary in Fishers, Indiana. When I looked for a brush blade attachment last year, the salesman who sold me original unit helped me and still had record of my purc&ase! Don't even think about getting this kind of service from a big box store. April 5, 2016
Rated 4 out of 5 by Solid build Well built tool. High torque with the km90. Too much so to trim gently along vinyl fence without tearing it up. Neighbor ran it over turning car around on my lawn. Bent it really bad. Straightened it in the fork of a tree. Been using it for a year since then with no problems. November 19, 2015
Rated 2 out of 5 by Problem with cutting line AutoCut feature is not that great, when I can keep line in it, it works OK but the problem is keeping line in the head or getting it to feed when it should. Have to take the head apart to get the line extended, not very time saving. April 6, 2015
