0 of 0 people found the following review helpfulPerfecta bomba para acoplar la antigual silent 100, únicamente tuve que calzarla unos 2 CMS. Funciona correctamente aunque el envío fue algo tardío habiéndola pedido un jueves por la mañana y no hubo moviento hasta el lunes, entiendo yo que será por el fin de semana de por medio, por lo demás ok
