Is it worth it?

One page per product, built the same way every time: what the Korean rating platforms say, what the formula actually does, whether the US version is the same thing, and a list of the numbers we could not confirm. We do not reproduce Korean review text — we link to it.

How these pages are made. Ratings and rankings come from Korean platforms and are recorded with the date we checked them. Specifications come from the manufacturer. Everything else is our own writing. We have not personally tested these products, and we say so on every page.
