Okay, so I've been using these Medela connectors for about a month now with my Swing Maxi pump and WOW what a difference!
First off - the comfort level is insane compared to the original parts. The flex design lets me actually lean back while pumping instead of being hunched over like a goblin. Major win for my back!
Installation was stupid easy - just popped them on my existing tubing and shields. No extra parts needed (though I did buy an extra set because... mom life).
The closed system actually works! No more panicking about milk getting into the tubes. Cleaning is a breeze too - just toss them in the sterilizer with my other pump parts.
Only tiny complaint? One connector started getting loose after 2 months of heavy use, but honestly that's pretty good considering how much I pump. Already ordered replacements!
If you're on the fence about upgrading your Medela pump parts - DO IT. These made pumping sessions way more comfortable and efficient for me.
