I have a spectra s2 pump and meddle bottles. Does this work for wide (spectra) to regular (meddle) collection bottle conversion?

No. This connects to Medela flange components, but the Spectra's shield/flange thing-y is too wide on the bottom. I tried to connect it "upside down" but the threadded parts are both on the inside (so like trying to connect two female plug-ends) and it did not work. I have ALL my stuff out bc I'm putting it away (YAY!) today.Here's the deal that I found worked wonders for me (I exclusively pumped). I use the Spectra S2 (best thing EVER!!) but I had a ton of Medela stuff and I like that you can pick your shield size. So I used Medela parts on the Spectra S2. All you need to do that (and use your Medela bottles) is to buy Maymom's little yellow connectors for Spectra-to-Medela. Presto- DONE!Another tip-- because I pumped so much, I, like so MANY other moms found that the Pumpin' Pals shields was a life saver. They don't hurt, and you can lean back. They go well with the Medela pump parts and Spectra S2 setup, because they just go where the shields went. On Spectra pump parts, since the shield is part of the flange, I don;t know how they get inserted or if it works well. But hey, if you've got Medela stuff laying around, those little yellow adapters are super-cheap, consider giving them a try! GOOD LUCK!!

Does it work with dr brown bottles?

No- not the standard (small) neck bottles. The skinny end goes into your Medela part that brings the milk from the breast into a container. This would connect that Medela part to a larger-mouthed bottle. So, without it, you can hook Medela bottles AND Dr. Brown's skinny/normal-necked bottles. But by adding this, you can connect your Medela setup to Spectra wide-mouth bottles. I do not know about Dr. Brown's wide-mouth bottles.
