I personally find it super bulky and it’s loud! It may just me but after using the pump it leaves this suction ring around my breast. If you don’t put the pump together correctly it will leak. The packaging is nice and it comes with cloth looking bag to transport the pump and some cleaning tools!
I have found these great. I get the same amount of breast milk from these that I got from my hospital pump. You need to use a bra that will hold them in place. It is good that they are portable and you can move around with them on. They are not as discreet as some more expensive models but you can pump in the car or wear a big coat/jumper if you want to disguise them out in public.
I tried both the S12Pro and the M5 and I prefer the M5. The S12 moves too much in the bra because the top part is in the strap’s way. I contacted Momcozy and their costumer service is excellent! They really want to make sure you are satisfied with your pump.
Best pumping system. I’ve tried three different brands to include the industrial hospital grades. These are better. Easy to pop on and go. The only think I don’t love is cleaning all the parts and re assembling.
