No currency shortcuts
We record the local selling price and date. We do not convert a foreign price and present it as local availability.
No import assumptions
Voltage, plugs, warranty and servicing are checked before any imported machine is discussed as a buying option.
No invented testing
Every page states whether the assessment is hands-on, editorially researched or limited to specifications.
