Research-driven buying advice
Dudproof
Real owners. Real deals. No duds.
Dudproof helps you avoid duds: products that fail, disappoint or cost more than they should. Every pick is built from independent lab tests, real-owner evidence, CPSC recall records and running-cost math, with every source linked. We don’t test products in person, and every guide says so.

How we research (and what we don’t do)
We don’t have a lab and we won’t pretend to. Instead, every guide stacks four kinds of evidence and links every one.
1
Lab results
Measured results from independent testers who publish their methods. When they disagree, we tell you.
2
Owner Proof
How products fail for real owners: forums, repair data and warranty terms. Never Amazon reviews.
3
Recall checks
Every pick is checked against CPSC recall records, with links to the official notices.
4
Costs + Dud Score
Running costs with the math shown, and a 0–100 Dud Score once every input is sourced.
