Feedback & questions

Tell us what to build
— and what we got wrong.

Quantdiv gets better when you push on it. Suggest the next category, flag a spec that looks off, or ask how the Value Score works. Real people read every note.

We're building this out continuously — new categories are added on a rolling basis and every spec is re-verified against manufacturer sheets and standards bodies. What you tell us here shapes what comes next.

Question a number

See a spec that looks wrong? Tell us the product and the figure — we'll re-check it against the source and fix it.

  • "The Coway 400's filter cost looks too low."
  • "Where does the CADR number come from?"

Ask how it works

The formula is published on every page, but if anything's unclear, ask. We'd rather over-explain than be a black box.

  • "Why is this ranked above a cheaper unit?"
  • "How do the sliders change the score?"

Request a category

Shopping something we don't cover yet? Tell us. Categories with real demand jump the queue — vote below or write it in.

  • "Do dehumidifiers next."
  • "I'd use this for robot vacuums."

Just tell us anything

Layout confusing? Missing a spec you care about? Love it? Hate it? All of it helps — send it raw.

  • "Add a column for filter type."
  • "The mobile table is hard to read."
