A documentary selection, a first impression, and a prolonged test are different tasks. We indicate what has been done in each case.

A test records the responsible person, product, variant, origin, dates, conditions, criteria, observations, and limitations. Samples, loans, and invitations are declared.

We do not simulate usage experiences with artificial intelligence. Result images must maintain comparable conditions. Samples and returns are recorded in the editorial panel.

The current edition contains documentary research and editorial proposals. No usage experiences or visits that have not been carried out are attributed.
