In my case I use ms180 this little girl also the good one. Suits for cutting off old trees and in May it's waiting to be used for rebuilding my old garden house.
But about disassembling and building new one garden house I'll trybto write separate posts.
Now my MS180 more than 9 years old, got it from my wife's father I tried to renovate it with some parts and I should say it works great👍
