My pump failed in 6 weeks. The pump is a fifteen dollar replacement part, so no thanks. That's not a solution.To Amazon's credit, they said they would accept the return, but I am waiting forever to get a postage-paid label snail-mailed to me -- and who knows how long it will take for the credit. Amex has a 90-day product guarantee, so at least I know I'll be protected by my cc if Amazon doesn't come through.
