Corrections

Found a wrong specification, a price that is way off, or a measured speed we should add? Please include:

• the machine (and its exact model or version, if you know it),
• what is wrong and, if possible, a link to the source (manufacturer page, review, datasheet).

We review every correction and update the page with a new “last reviewed” date.

Suggestions

Suggest machines worth adding. We prioritise compact models you can actually buy on Amazon in Spain or the US, and independent noise measurements of any model in the guide.

What we cannot do

We cannot provide one-to-one support for setting up your network. Our guides cover the most common questions.

Manufacturers and retailers: we do not accept payment for reviews or rankings. See our affiliate disclosure.
