On the basic metrics alone, the score was 65.8 and the rank 4. The score is now 42.9 and rank 5 (▼ 1 place). The difference comes from buying motives: they measure what the buyer asks before deciding.
Lammin Ikkunan vahvuus on hintojen läpinäkyvyys: oma ikkunaverkkokauppa näyttää euromääräiset alkaen-hinnat ilman kirjautumista ja kertoo toimituksen ajankohdan. Ikkunat valmistetaan mittatilauksena kotimaisesta männystä, asennus on saatavilla ja operoiva yhtiö Lammin Ikkuna Oy (Y-tunnus 1454666-1) on ilmoitettu. Läpinäkyvyyttä laskee se, ettei U-arvoa eikä takuun tarkkaa pituutta kerrota ja että jälleenmyyjäverkostoa ei listata.
