The comes up a lot. Just because it says Stihl on it I never assumed it was. I hope others are better consumers than that. But you make a good point when someone is trying to rip someone off they rely on stickers. Someone hand me a saw and say this is a Stihl it better be. If I see an orange white saw it without stickers you might think crushed rebuilt saw. If OEM is what you are buying you better look it over and ask is this a genuine Stihl? If they say yes it is and you pay them that's theft by taking. I worry more about buying a used saw. No telling how that thing has been abused. Just asking the seller is fraught with trouble. They likely will lie to you. Just look at the excellent saws on Craigslist. That's puffery. The other is theft.
