I'm a bit skeptical - I wouldn't be surprised if you send back new saws instead of fixing them. Or, if I send you one saw, and you send back two? Treestuff is always giving things away. I think the whole company is a front by some billionaire quack who's hellbent on making all the other suppliers look like assholes. They seem oblivious to the profit motive that all sensible economic endeavors utilize. Nuts!
