What is the implied warranty of merchantability and how does it protect consumers?

The implied warranty of merchantability is a default guarantee imposed by law under UCC Section 2314 on any sale of goods by a merchant who regularly deals in such goods. It means the product must pass without objection in the trade, be fit for the ordinary purposes for which such goods are used, and conform to any statements on the label. A blender that breaks after one use or a piece of clothing that falls apart in normal washing would violate this warranty even if no express written warranty was provided. Sellers can disclaim this implied warranty by conspicuously using language like 'as is' or 'with all faults,' but many states restrict or prohibit such disclaimers in consumer transactions.
