Warranty Basics That Apply to Any Brand

The general rules behind every manufacturer warranty — your rights, what proves coverage, and where registration actually matters.

• Manufacturer warranty and an extended/retailer 'protection plan' are two different things — the manufacturer warranty is free and covers defects; an extended plan (Geek Squad, Asurion, SquareTrade) is a separate paid service contract sold by a third party, not the maker.
• The Magnuson-Moss Warranty Act and the implied warranty of merchantability protect you beyond the written terms — this federal law preserves an implied warranty that goods work as expected, and a written warranty can't disclaim it while it lasts — baseline protection even after fine-print limits.
• Keep the receipt / proof of purchase — it's what actually proves coverage — almost every brand requires a dated proof of purchase to validate a claim and set the start date; without it a valid claim can be denied.
• Many credit cards add extended-warranty coverage automatically when you pay with the card — Visa, Mastercard and Amex have historically extended the maker's warranty (often by up to a year) at no cost on eligible purchases — check your card's current benefits guide.
• In the US you usually do NOT have to register a product to be covered — registration mainly enables recalls and marketing; some brands (Instant Pot) state in writing that not registering won't reduce your rights. Exceptions exist where registration unlocks an extension (LG, SharkNinja, Bosch lasers).
• 'Warranty void if removed/tampered' stickers are often unenforceable — the FTC has warned that tie-in rules and warranty-void stickers generally violate the Magnuson-Moss Act, so opening a device or using third-party parts usually can't void coverage unless it caused the damage.
• Find the serial number before you start a claim — warranty status is keyed to the serial/model number (Apple, HP, Dell, Lenovo lookups); it's on a device sticker, under the battery, in Settings/About, or on the original box and receipt.
• Whether an extended warranty is 'worth it' depends on price, failure odds and overlap — it makes sense when the plan is cheap relative to the item, the product is failure-prone or costly to repair, and it adds real coverage (e.g. accidental damage) you don't already get from the maker or your credit card.

Never lose a warranty again

Keep every product's warranty, receipt and expiry in one place — WarrantyKeep stores each product's purchase date, receipt photo and warranty length, and reminds you before it expires.
