We search Amazon like a shopper
Every guide starts with the same Amazon.com search a real buyer would run, such as "french door refrigerator" or "pellet grill". We collect every product on the first page of results.
- 2
We filter out weak options
Products without enough buyer ratings, with suspiciously low prices or that do not truly belong in the category are removed. We keep up to 15 of the most serious candidates.
- 3
We collect the product facts
For each candidate we gather the current price, the Amazon star rating, the number of ratings, the key features and the full technical specifications.
- 4
We read what buyers say
We read the buyer reviews of every finalist, including the critical ones, and count what keeps coming up: a part that fails, a size that runs small, a feature that works better than promised.
- 5
We score every product
Each guide has its own criteria, chosen for that category, and each criterion has a weight. Every product gets a 0 to 10 score on each one, and its Ranklim score is the weighted average.
- 6
We write it and check it
Felipe Iglesias writes every guide, and the Ranklim team reviews it before it goes live: no invented facts, no hidden sponsorships and clear, honest trade-offs for every product.
What decides the ranking
- Real capability
- What the specs say the product can actually do, not the marketing headline.
- Value for money
- How much performance and quality you get for the price you pay.
- Buyer evidence
- The star rating combined with the number of ratings. A 4.6 from 3,000 buyers beats a 4.9 from 12.
- Fit for purpose
- Who the product is best for, so every pick in a guide serves a different kind of buyer.
What we don't do
We don't test products in a lab or at home, and we never say we did. Our rankings come from the spec sheets, the prices on Amazon.com and what verified buyers report, read one review at a time.
We also never invent specs, prices or quotes. If a detail isn't in the product data or the manufacturer's documentation, it isn't in our guide.
Our independence promise
No brand, seller or manufacturer can pay to be included or to move up in a Ranklim guide. We earn a small commission from Amazon when readers buy through our links, at no extra cost to them, and that commission is the same whether a product ranks first or tenth. Prices and ratings change often, so every guide shows the date the price was checked. Learn more about Ranklim.
