Lead Test Engineer · BuyingBench

Alex owns BuyingBench's test protocol and scoring criteria. Every head-to-head matchup on the site is built against that protocol — the same criteria applied the same way to every product, and a bias toward specs you can actually verify. If a claim can't be traced to a checkable figure, it doesn't make it into the article.

How Alex works

Every head-to-head on BuyingBench starts from a written protocol — the same criteria, applied the same way, to every product in the comparison. Power draw, capacity, build materials, battery life, noise: each one has to come from a figure that can be pointed at and checked, not a subjective impression.

Where an article is a hands-on lab test, that means measurements taken from the unit itself. Where it is a research-based comparison — which is what BuyingBench’s current coverage is — it means manufacturer-published specifications, aggregated verified-buyer feedback, and cited third-party sources, compared against those same criteria. Every article states which kind it is on the page.

What Alex won’t write

  • A comparison that doesn’t disclose whether the product was physically tested
  • Marketing claims passed through uncritically
  • “Winner” calls that come down to a vibe instead of a number

If a product’s datasheet and the aggregated real-world reports disagree, that disagreement goes in the article rather than getting smoothed over.
