How We Review

Last updated: October 27, 2026

What we compare

Each guide names its ranking criteria at the top of the page, for example magnification, lens size, build, guarantee and price. We read the specifications published by each seller and by marketplaces such as Amazon, and we compare them side by side.

How compensation works

We earn commissions from some of the sellers we feature. This compensation may influence which products we feature and the order in which they appear. It does not change the specifications, prices or guarantees we report, which come from the sellers themselves.

What we do not do

We do not publish invented reviews or testimonials. Ratings from marketplaces are quoted with their source and date.

Prices and offers

Prices, discounts and guarantees are set by the sellers and change often. We note the date we checked them. Always confirm on the seller's site before buying.
