How we compare

We don’t test machines in a lab, and we won’t pretend to. Here is what we do instead.

Specs come from the maker

Every spec in our database comes from the manufacturer’s own product page, or from the brand’s official distributor when the maker publishes no spec page. Each machine page links to that source and shows the date we checked it. The current data was checked on November 13, 2026.

Blank means unpublished

When a maker doesn’t publish a spec, we write “Not listed”. When a maker’s page contradicts itself, we leave the value blank and explain why in the machine’s notes.

Sales figures are Amazon’s own

The “bought in the past month” numbers are the badges Amazon.com shows on each listing. We record them with the date we saw them. They are a snapshot, not a ranking we invented.

How we make money

Some links go to Amazon with our affiliate tag. If you buy, we may earn a commission at no extra cost to you. It never changes the specs, the fit results or the order machines appear in. Details in our affiliate disclosure.

Found a mistake?

Specs change and pages get updated. If something here doesn’t match the maker’s page, we want to fix it.
