I have a well USED one; as well as 5-6 worn-out(?) ones that I grew frustrated when they finally failed to start for the umpteenth time and bought a new one.
He gave me a Stilh with a 20 inch bar. It was a great use in CT, because of how often branches or entire trees fell around my house. I moved to Ohio in 2020, and didn’t use it, since my property was smaller and only had 2 small trees.
Last week, I noticed one of them was dead. After not starting it, in almost 2 years, it started in less than 30 seconds. Took about 20 minutes to cut that tree to the stump.
