I own the top of the line Kenmore sewing machine that Sears sells.... it has been in to be repaired 5 times in the year that I have owned it, and has been replaced twice--within their 90 day customer satisfaction guarantee. I FORTUNATELY bought the 5 year warranty that fixes or replaces the machine at no cost to me..... If you sew very often, YOU WILL NEED THIS WARRANTY!!! The bobbin case wears out every three months on mine, because it is a cheap plastic part. I have been soooooo thankful for my warranty, because otherwise, I would have been without my machine!!!
