On the basic metrics alone, the score was 64.5 and the rank 4. The score is now 39.2 and rank 5 (▼ 1 place). The difference comes from buying motives: they measure what the buyer asks before deciding.
Ilmasi Oy tarjoaa harvinaisen suoran hintalaskurin, joka näyttää puhdistuksen hinnan heti, ja esittää esimerkkihinnat venttiilimäärän mukaan (245-495 euroa). Toiminta-alue kattaa suuren osan Suomea ja Y-tunnus on esillä. Kirjallisen pöytäkirjan toimittamista ei mainita, ja puhdistuksen sekä säädön suhde jää osin tarjouksen varaan.
