Saved my pumping journey
Has saved my pumping journey. After using a rival wearable brand for the first 4 weeks, which slowly stopped working for me as elastic nipples were getting more painful, I knew I had to switch pumps to something that suits elastic nipples better. Because this has a longer tunnel, I don't have the issues I had with my old pump, there was a small flange sizing kit inside my box (but reading other reviews, some people didn't get this previously) and I'm no longer in pain pumping and my supply is gradually increasing again to keep up with the demands of my twins. It's bulky, and takes attention to put on properly , and the suction is STRONG so I keep my settings very low. Also recommend using coconut oil on the flange to reduce friction/pain. I'm a fan of the larger cups too, for me the capacity is enough and better than my old pump which I'd have to sometimes empty before continuing the pump session. Love the fact I'm not worrying about charging it several times a day too.

Best decision
Money well spent! I really needed an additional pump on the go for when I’m not using my Spectra. I did a lot of research and ended up going with this one. Best choice ever, I get almost the same amount out as my hospital grade pump with the convenience of being able to move around and do things at the same time. To make sure it works well it needs to be set up properly and you need to get the right flange size (which is not included in the package but you can get various sizes on here for very cheap. I know the price might be an investment but in my opinion you won’t regret it.

Makes milk output MUCH higher - essential purchase
I knew which size to get as I purchased the Momcozy pump which came with a measuring gage. The flanges that the pump comes with are way too big for the average nipple and so it dramatically reduces the amount of milk you will get. Make sure you measure for which flange size you need and don’t just use the one that comes with the pump!
