I’ve been using Lacte Duet for 4 months now, and my breast milk has been increasing. From only 3oz and now to 6-8oz. I'm a working mummy and previously was using a manual pump & a single pump from another brand, it was very tiring. After owning a Lacte Duet Double Electric Breastpump, it saves a lot of my time. Many thanks to LACTE DUET.
