I quite like this pair of breast pumps. When fully charged they can be used for approximately 4 30-minute pumping sessions. The suction is good and didn’t hurt at all. I also got the same output from this pump when comparing to my wall pump. With that being said, there are a few things that could be better. For example, cleaning the parts is a bit of a pain (there are 5 parts if you count the flange insert); and they won’t work until everything is completely dry. Due to this it is very time consuming if you want to use this more than once a day. The manual could also be more detailed on how to clean and assemble, or provide FAQs on troubleshooting, especially for those who are clueless about wearable pumps or new to pumping like me. However, customer service was top notch so all my questions were answered. Overall I would still recommend this pump.
