These attach directly to my Spectra S2 flange. It's nice to have an extra set of storage bottles and it's a good value for what you get. Sometimes I use them to differentiate mixed formula from breastmilk in the fridge. The only downfall is it is extremely hard to clean the lid. There is a silicone liner on the inside that gets residue stuck on it or underneath it. They also don't always stay on the lid. I think they are meant for a better seal, but really they just hold onto the filmy part of the milk.
