Review on Maymom Wide-Mouth Milk Storage Collection Bottle With SureSeal Sealing Disk; Compatible With Spectra/Motif Luna/Ameda MYA/Bellababy Pumps. Can Replace Spectra S1 S2 Bottles, 6 Pc (4.7Oz/140ML, 6Pc) by Robert Viher

I’m a working and pumping mom and these bottles are perfect to pump into! I needed one larger bottle to pump into just for one breast. They are durable, come clean easy and so far (2 months of use) the numbering on the outside is showing no signs of wear. The measurements are accurate too. They fit directly onto the wide mouth flanges of my Spectra S2 tightly and with no issues. The only thing I don’t like is that sometimes they do leak and I’m not doing anything out of the ordinary with them. I put them standing up in the cooler bag, put that right side up into my pump bag and they go to and from the pumping room and to and from my car. The leaking is not much, maybe 1/4 of an oz, but all us pumping mamas know it’s hard and losing anything we pumped sucks. I also want to say the leaking doesn't happen every day, maybe 1-2 times every other week, but it does happen. Overall I’m very happy with them and reccomend them!
