Buying guides that tell you how they work.
WorldSift helps people choose expensive products with less guesswork. This page explains what we do, how we compare products and how we are paid.
What we do
We write plain-English buying guides and build tools, like our e-bike finder, that match your needs to products sold by partner stores. We focus on high-ticket categories where a wrong choice is costly: e-bikes, mattresses, power stations, standing desks, 3D printers, robot vacuums and more.
How we compare products
- Specifications, prices and ratings are collected from the brand store pages, and the date is shown next to them.
- Fit scores in our finder are WorldSift estimates based on published specifications. They are not lab tests, and we say so on the page.
- Customer ratings come from the brand store. Brands may show mainly positive reviews, so we label the source and treat ratings as one data point.
- We only summarize reviews we have actually read, and we say how many.
- When information is missing, we say it is missing instead of guessing.
How we make money
Some links on this site are affiliate links. If you buy through one, the store may pay us a commission at no extra cost to you. Commissions do not change the price you pay. We currently list stores we have joined through affiliate networks, so our selection is limited to those partners. Read the full affiliate disclosure.
Our limits
We do not sell products, we do not test products ourselves yet, and we cannot guarantee that prices or stock are current. Always confirm the price, delivery area and return policy on the store page before you order. Check local laws, especially for e-bike speed limits.
