A lifetime guarantee promises refills on dropped units forever. Its real worth equals the provider's lifetime, not yours. In an industry where suppliers vanish routinely, "lifetime" is a bet that the counterparty still answers email next year.
A guarantee is a liability someone has to keep paying. Unlimited-duration liabilities from businesses with famously short lives price themselves.
The graveyard documents how often this industry's names stop resolving, and every one of them took its lifetime promises down with it. A bounded 30-day window from a provider who answers support beats an unbounded promise from a storefront three hops from its supply.
Stock that rarely needs the warranty: high-retention grade whose chart stays flat. Sellers price warranties from their own drop expectations, so a modest, concrete promise on good stock usually signals better than an infinite promise on mystery stock.
Read guarantee terms where they should live: on the service listing and in the refund policy, not in support-chat folklore.
Not always fake, just capped by the provider's lifespan and terms. Treat lifetime as marketing for "long window", then judge the provider's stability and support instead of the adjective.
A concrete, answerable 30-day window from a stable provider usually beats an untestable forever from an unknown one. The window you can actually claim is the real product.
The standard exclusions: renaming the handle, going private, deleting the target, or platform action against your account. Inside those rules, drops are the provider's problem during the window.
