Questions worth answering before you spend

Do expensive sheets actually last longer?
Thread count is a marketing number. Fiber, weave and finish are what decide whether a sheet survives its thirtieth wash.

We compared the carry-ons everyone asks about so you do not have to
Softside, hardside, aluminum and 'smart'. Wheels and weight separated the good bags from the bad ones; brand and shell did not.

What “clean beauty” does—and does not—mean
There is no legal definition. Here is what the label usually signals, and what it never guarantees.

The truth about extended warranties
They are priced to be profitable for the seller. That tells you most of what you need to know.

When the warehouse-size package costs more
Unit cost is on the shelf tag for a reason. It is not always in the big box's favor.

Are premium hair dryers better or just faster?
Faster and quieter, in our bathroom. Better for your hair, according to the manufacturers — and unmeasured by us.

What a lifetime warranty usually leaves out
Airline damage. Cosmetic wear. Normal use. Which is to say, most things that happen to luggage.

Why so many smart-home products stop feeling smart
The hardware lasts ten years. The app lasts until the next reorganization.

How we read owner feedback without being fooled by it
Sort the complaints by date and look for the same word twice. Ignore the enthusiasm; it tells you only that the box arrived.

Sometimes the right answer is to keep what you already own
A recommendation site that never says 'do not buy anything' is a store.

How to spot a fake discount
A discount is only real relative to something someone actually paid. Here is the check to run before a 'sale' decides for you.

The subscription is the product
When a device needs a monthly fee to do what the box says, the box is lying by omission.
