What are the key things to look for while choosing a breast pump?

1. Portability If you're using it mostly at home or in the office, you can consider a hospital grade breastpump. it's bulkier, but it does the job better. I'm using Spectra S1. If you need a breastpump which can be placed in your bag, get Spectra 9+ or Medela Freestyle. 2. Noise level Whether it's in the dead of the night or in the office, it's better to have a pump which is not that noisy. Spectra S1 performs well in this aspect. Avent pumps are really noisy. 3. Budget Of course, your budget matters. I purchased my pumps from Qoo10 and it's a lot cheaper compared to those with local warranty. Product wise, it's exactly the same thing.
