I had been using the Willow Go’s. They were uncomfortable and big. I ordered the MomMed S12’s, and to me, they are much better. The silicone flange is more comfortable than the willow’s plastic flange. The Mom meds are smaller yet just as effective. I also don’t like how I can’t see what level of suction I’m using on the willows or how long I’ve been pumping. The mommeds show what level I’m on and how long I’ve been pumping. I could not bend over at all with the willows. They would spill even with the stopper on them. The mommeds design allow me to bend over some without spilling. Overall, the mommeds are great!
Love these I saw a girl talking about these on TikTok and how amazing they were and she didn’t disappoint! Not only did the hold 7oz but the pour is so smooth as well!
I have tried other wearables and didnt respond at all. 30 minute pumps only resulted in like one ounce and i wouls still feel full. I almost gave up on wearables completely and decided to try the s21 from reviews on TikTok. I'm sooo glad I did! I can officially leave the house and not worry about missing a pump session. My favorite thing to do when Im out and about is to power pump. This is the output I'm getting!! I'm so impressed. My normal output is very comparable to my tried and true--my Baby Buddha!
My first wearable pump and I absolutely love it! They are comfortable and really get the job done
I love this pump. Its not really silent as advertised but no other complaints
