The 10-Year Buying Checklist
The ten checks every record in this library passes through, on one page. Before something enters the home, top to bottom. A purchase that can answer all ten usually lasts ten years.

- 01
Warranty — the exact term, in writing
How many years, covering which parts — and is the failure-prone part (motor, cylinder, electronics) inside or outside the term? A warranty that excludes the part that fails is a shorter promise than it looks.
- 02
Parts supply
Are wear parts sold individually, by name, at a price that makes repair worth it? A product whose parts cannot be bought has a lifespan equal to its weakest component.
- 03
The repair route
Who does the repair — the maker, a service network, any competent local shop? A documented repair path (published manuals, standard fasteners) outlasts goodwill.
- 04
Maker continuity
How long has the maker existed, and does it still answer for products sold decades ago? A warranty is only as durable as the company behind it.
- 05
Consumables
What does a year of filters, pads, blades, or gaskets cost — and from how many sellers? A cheap machine with captive consumables is an expensive machine.
- 06
Cost per year
Price divided by honest years of use, plus upkeep. The one number that lets a dear pot and a cheap pot be compared fairly — the calculator below does the arithmetic.
- 07
Return terms
The window, the condition rules, who pays return shipping — read before the box is opened, not after.
- 08
Authorized sellers
Is the seller on the maker's authorized list? Warranties often start — or fail to start — at the point of sale.
- 09
The model number, not the series
Successor models inherit names and shed parts. Price history, reviews, and spare parts attach to the exact number, not the family name.
- 10
The when-not-to-buy condition
What state of the current object, or of the budget, would make the right choice “not yet”? Decided in advance, it is a check. Decided at the store, it is a rationalization.
Where these ten come from
The list is the working method of this library, compressed. How each check plays out on a real object is in the records themselves — the catalog holds all of them, and the five axes behind the method are set out in five questions before you buy.
Check six is arithmetic — the cost-per-year calculator does it →
