They do not honor it well and often blame the owner. But, chainsaws are very reliable on the whole and if they do have manufacturing issues blow up in the first 10 hours. The Echo saws are still a good buy. All the companies hate honoring warranties.
The Makita saws are fantastic as well. I am converting my work fleet over to them due to cost of parts and ergonomics.
