Most of them I have looked at, still had the Box store"Starting instruction and warning" stickers on them.
All of the Box stores have a very generous "No questions" return policy which leads to all manner of hijinks.
Windstorm hits, joe doofus buys a 455 and cleans up a downed tree,dulls the chain, throws the chain, floods it, can't figure out the brake etc. then takes it back for a refund, or exchange for another with a sharp chain on it.
Same thing happens with Generators. It got so bad that our local TSC adopted an exchange only policy and no refunds, on saws and Generators.
What's goofy is the same saws then get sold at an honest ta goodness dealer, and very few ever come back in, because before they leave, the dealer walks the buyer through running the saw.
I have seen 'em go on E-Bay for 299 bucks, but anyone looking for dealer support and warranty coverage would be better off spending another 25-30 bucks at a dealer.
The really nice thing about refurbed 455's is guys with Orchards can buy half a dozen and turn the pruning crew loose and not worry.
It's tough to bust the things,They hold up to getting thrashed, and the warranty covers everything but straight gas. If one or two grow legs and migrate to Texas all of a sudden, it's a lot better than losing 600 bucks each.
Stay safe!
