I am very satisfied with my Lacte Duet. So far I've been using this for 10 months. I will recommend Lacte Duet to whoever may ask for my opinion =). The Silicone Breastshield is good, suction can be adjusted (so far the highest level I used is 4). By pumping with the Lacte Duet, it can empty my breast in just 15minutes. Thanks Lacte for the great product!
