M5 replacements
Perfect fit! I am an exclusive pumping mom and sometimes need to be on the go. I had used down my original parts and these came in fast and worked great.

Amazing item!
I have reordered this product multiple times and will continue to! It is my favorite cleaning brush for bottle nipples and pump parts, it makes me feel good knowing I’m getting a good clean for my baby’s things!

Beware! No suction with replacement silicone shields!
I never write reviews. But this is ridiculous….Thinking that buying directly from the manufacturer would be the right way to do this, I was wrong. I bought one replacement silicone shield thinking I was getting a two pack and realized I needed to purchase another - but my husband washed the single one and put it on the pump for me. I noticed one side - the original silicone shield - the suction was fine. It wasn’t doing anything on the other side with the new shield. When I got the second one, I put both new ones on and I realized the problem persists with both new shields. I put the two old ones back on and it works fine. This is so dumb and such a waste of money - momcozy is one of my favorite brands and I actually had no issues with the M5 pumps otherwise but this is really frustrating. I could see this as an issue if purchasing from a third party and the fit was off, but come on… disappointing and creates doubt with the brand

Wore out quicker?
These seemed to wear out quicker than expected , meaning I had to replace sooner than anticipated. However, overall good product and accompanies a good pump.

100% recommend
I ordered 2 pairs since the original ones started to get ugly after sterilization. Honestly, I like the replacements more than the original ones that come with the pumps. These are a bit firmer and don't leak. It's the best purchase I've made, and it's also very affordable.
