Rated 3 out of 5 by Negotiate a Different Head Construction of this tool appears to be similar to other Kombi accessories. It engages well with the Kombi power system and spools up appropriately to trim. I purchased this accessory with a Kombi power head, a bed redefiner, and straight shaft edger. Of the three accessories purchased, the FS - KM 's line dispensing system has proven to be the most disappointing. After several attempts to use the FS - KM line trimmer I am writing this review to alert potential buyers to see if their Stihl dealer will supply a different design head. Multiple attempts were made to trim only to have one of the lines break flush with the trimmer's head. Each time the line broke, I could not get the line to feed and would have to remove the head's cover, pull the line back out the side that had broken, and re-cut the opposite side to match length, wasting line. Any contact with larger weeds or walks would cause one line to break flush with the dispensing head. My limit each time out was having to repeat this drill 4 times. After a week of frustration I removed the head and replaced it with one that allows the use of a 16.5" piece of straight trimmer line. With this aftermarket head in place, and replacement line, the trimmer works beautifully. Unfortunately, I cannot recommend the FS - KM due to the poorly designed "bump" head and fragile OEM line with which it is equipped. If equipped with a reliable head/line system, I would rate this accessory a good value. As it comes, if you have to buy an additional head to achieve reliable service, its value is suspect.
