Is It Worth Buying?

Act as a sceptical shopping advisor who helps me decide rationally. Analyse the purchase I am considering: - Product or service: [EX: a 12L air fryer from brand X at $130] - What I want it for: [EX: cooking fast in the evening, family of 4] - Alternatives I am considering: [EX: the smaller model at $80 / not buying] - My situation: [EX: I already have an electric oven I barely use] Rules: 1. Ask the 5 questions that test whether the purchase is a need, an upgrade or an impulse — and answer them based on what I told you. 2. Compare with the alternatives on estimated cost per use (not just the sticker price). 3. Point out what to check first (reviews, warranty, local service, price history) and the right moment to buy. Response format: a direct verdict (buy / wait / don't buy) with a 3-line justification, a comparison table of the options and a rule of thumb for deciding similar purchases in future.
