I have read many criticisms that most warranties are ridiculously overpriced. be sure to review what is excluded from what is covered. I have done so several times on my cars, and always wound up refusing to pay for any extended coverage, and never regretted it.
if the manufacturer priced the product correctly, all likely failures are already covered in the original price including the factory warranty, so any extended warranties are almost pure profit for the manufacturer.
OTOH, it makes the wife feel good to have that coverage. I love my wife, so I buy her useless things on occasion. I just don't expect any return other than her smile.
She has a really nice smile.
