Query: Lid malfunctions

My lid began its consistent malfunctioning very soon after purchase.The warranty service requires customers to pay to ship the lid to them with a check for $9.95 for return shipping, which would have cost me about half of what I paid for the item.This is one of the worst products I have ever made the mistake of purchasing, and I regret disregarding the featured negative warnings from previous years in favor of the 4.5 star rating, positive recent reviews, and posted "solution".
