Review: Great replacement parts - For those that do not know, the Doc Browns Anti-Cholic bottles are great bottles that work as advertised, particularly in their anti-cholic function. This stem is the feature that permits that function. The bottles also travel well...which is how we kept loosing these stems and stem caps. So I bought a few more. Bein as how these are the exact same brand and part they function in the bottle well. I just wish that Doc Brown would amend their bottle brush design to include a brush that would effectively clean this part. But I've never had one break, the part itself is great, and the bottle design as a whole fulfills its promises.
Review: Great replacement parts - Perfect replacements. We had gotten some Dr browns bottles second hand and needed new replacement vents. Works great!

## Questions & Answers

**Q: Will these only fit the options bottles?**
A: The bottles themselves are all the same. So these will fit any bottles. I’m not 100% sure if the cap that holds the nipple will fit from the natural flow, but I’m sure it will.

**Q: will these fit evenflo bottles?**
A: Thank you for your inquiry.  We have not tested the Dr. Brown’s Natural Flow® Options+™ Replacement Vent Kit, 2-Pack, Narrow in an evenflo bottle.

**Q: Can someone please tell me what these pieces are called?**
A: The parts in this post are the travel disks, reservoir tubes and vent inserts.

**Q: Do you have the 4 oz vent kit for 4oz dr Browns bottles**
A: Bed Bath and Beyond
