Review: Made of thin abs plastic. I thought they would be more durable for the price. If I didn't need them I would have returned them.
Review: scarsa la tenuta in controflusso, nel mio caso ho risolto con serranda motorizzata con flap dotato di guarnizioni di tenuta ....... che ha ben altro costo rispetto a questa serranda di plastica. piuttosto che niente meglio piuttosto, ma non aspettativi chissà quali prestazioni, per quello che costano un tentativo fatelo, magari per le vostre esigenze sono sufficienti.

*by @***D on 31 October 2017*

Fácil de instalar si el tubo es de las dimensiones adecuadas. En mi caso el tubo era un par de milímetros mayor y lo he colocado con un poco de cinta para fijar e impedir paso de aire. Lo he combinado con extractores que ya tenía y también en ventilación pasiva con el tubo en horizontal, va perfecto.
