If something fails - absolutely! If nothing does…no, but that’s kind of always the gamble with a warranty.
Generally folks have been charged between $250 and $1250 (based on folks who’ve stated their cost on the forum) when they’ve had to send their machine in for a repair or exchange. I’ve had mine for 4 years and haven’t had anything (knock on wood) go wrong.
BTW, if you’d like to read more about the warranty, Dan just covered it in his announcement last night.
