How to read this

Sources: the product's public listing and reviews, its published price, and public forum threads. Revenue is an estimate unless marked verified by the founder; the formula and its inputs are on the full x-ray. Complaints are grouped by a language model and each quote is a verbatim excerpt, linked to the original review. Build difficulty is a model's reading of the listing and the complaints, not a measurement. Figures are a snapshot of Nov 4, 2026. Corrections: corrections.
