Actually, I modded my first one and put cuts in the other side and I asked but they won't deal with that one, but the second was stock and no problems replacing it at all.
Never even asked for a warranty card or a receipt or asked about the age, either.
I just sent in in and as soon as they got it another was shipped to me priority mail and the only cost to me was shipping it to them.
I am going to get a Raptor digger from their sister line at Predator tools for next season.
I bet they have the same type of no worry replacement situation on that one, too.
A good thing for a guy like me because I seem to be extra hard on using these tools.
Other types would never stand up at all or for very long to the abuse I usually dish out.
