Zaobstaral som si tento produkt... a prekvapilo ma, že ukazuje stále nulu (aj PM 2,5, aj PM 10). Na odporúčanie Alzee som si produkt spároval s appkou (čomu som sa pôvodne chcel vyhnúť), aktualizoval firmvér ... stále nuly. Či doma, či vonku, či v zaprášenej pivnici. Na odporúčanie Alzee som urobil test sviečkou. Pár centimetrov od prístroja a už nabiehali čísla ako 1-2. Po sfúknutí to vyskočilo na ~60, ale k nule kleslo za asi 10 sekúnd. Keď sa však pozriem na stránku hydrometeorologického úradu, čakal by som skôr hodnoty 5-15 μg/m³. Má niekto z používateľov rovnakú skúsenosť? Alebo ide o chybne kalibrovaný výrobok a mám ho vymeniť v rámci záruky?
