I have 2 KM 110 one is new one is 6 years old.
I just bought a KM 55 for my back up but may use it all the time.
String trimmer, works real good and is easy to load trimmer line. The only down fall is the part you "bump" wears out fast.
Curve shaft edger, works good, had to replace the defelector a couple of times.
Adjustable hedge trimmer, works real good and being able to "bend" isreal nice.
Pole saw, works ok, the chain tends to "grab" small branches.
Extension, great investment for the saw and hedge trimmer, if you dont have one get one, I will say the stuff can get real heavy and Id be real careful around windows.
Bed edger, just got so far Im unimpressed, however I havent used it that much.
Brush cutter, its worthless so Ive only used it a couple of times, eventually Im gonna try some different blades
I likley get the tiller this year, I gave my mantis away
