Wonderful pump – Very efficient pump! I had the pump for 4 months now and it has helped with my milk supply. It is light, quiet and portable. The cost is much less than Medela it Avent. I love also how easy the parts can be cleaned and assembled. It is also easy to get spare parts from the website so there is always clean Breastshields to use. You can also get spare bottles from avent which fits perfectly with the pump! I would recommend this pump to anyone.
