Why should I trust a review site that uses affiliate links?

You shouldn’t trust any review site on its word — including ours — so we structure the incentives where you can see them. The disclosure is on every page: some of our links are affiliate links, and if you buy through them we may earn a commission at no extra cost to you. What we put against that: verdicts anchored to things you can verify yourself — a seller’s published measuring guide, its stated remake policy, and per-window prices we quote at a benchmark size and date — plus honest cons on every review and coverage of sellers who pay us nothing. When we can’t verify a claim, the review says "not published" instead of guessing, and an affiliate relationship never overrides a weaker measuring guide or a stingier remake policy. Check our work; the citations are the point.
