Luka is the editor of Analysis of Fear. Nobody here buys or tests products: each article is built from manufacturer specifications, manuals and warranty terms, published standards, regulator data and recall notices, and every figure links to its source. First drafts are produced with AI writing tools; Luka checks them against those sources, edits them and signs off before publication, and handles corrections sent to support@analysisoffear.com.

An electronic stud finder measures capacitance through the wall surface. Anything denser than empty cavity reads as a stud — including the cable you are about to drill into.
Every chew toy eventually fails. The question that decides whether that is a nuisance or a vet bill is what shape the pieces are when it does.
Cats that stop using a litter box are usually not being difficult. The box is frequently too small, too covered or too few — and all three are fixable for very little money.
A collar is fine for a dog that does not pull and a real risk for one that does. A harness fixes that and introduces a different failure — escape — which is entirely about fit.
Fountains attract some cats to drink more, though the hydration studies are mixed. They also grow biofilm in places you cannot see and fail when the pump silts up — which is a weekly job, not an occasional one.
SPF 50 is tested at 2 mg per square centimeter. Studies of real use repeatedly find people apply a quarter to a half of that — and protection falls at least as fast as the amount does.
A toothbrush handle is discounted to almost nothing several times a year. The heads never are — and over five years they cost several times what the handle did.
Cartridge handles are given away because the cartridges are where the money is. Over ten years the difference between systems runs into hundreds.
The underlying science is real and the consumer devices are frequently far weaker than anything tested. The gap between the study and the mask is where the money goes.
The membrane almost never fails. What fails is the treatment on the outer fabric, and once that goes the jacket stops breathing and your own sweat condenses inside it.
The number on the bag is usually the limit rating — just warm enough curled up, not comfortable — and it assumes an insulated pad you may not have bought. Both mistakes are made on the same purchase.
The words are used interchangeably in shops and they mean different things. A filter stops bacteria and protozoa; viruses go through it. Where that matters depends on geography.
