3. A Comparison of Medela Sonata Flex and Medela Pump
Medela Pump used to be the most trusted choice among Medela breast pumps until the Medela Sonata Flex version came into play. Assuming that newer versions are always better than the older ones may not be entirely accurate. In reality, compared to the newer Medela Sonata Flex, the Medela Pump has a larger and bulkier body, weighing around 1kg. The design of the pump has 2 tubing ports and 1 cap for single pumping. The funnel comes in one size, 24mm, with no silicone insert. It lacks an anti-backflow valve, so mothers need to be cautious as milk may easily flow back into the motor. Additionally, the Medela Pump is more affordable than the Medela Sonata Flex.

Accordingly, the full price of the Medela Pump breast pump is 4,890,000 VND, and the compact version of the Medela Pump is priced at 3,990,000 VND. Meanwhile, the price of the Medela Sonata Flex breast pump ranges from 8 to 10 million VND, depending on the seller.
4. User Reviews of the Sonata Flex Breast Pump – Is it worth the investment?
