    These come in so handy! Jul 02, 2022

    Absolutely necessary if traveling with Dr. Brown’s bottles, as they leak without these travel caps. Easy to use & they do their job, but they can be painful to get off due to raised lines on the lid. Feb 25, 2022

    We’d use these to pre make bottles and then just put the bottle in the warmer. Worked amazing! Especially for those nights when you are exhausted. Feb 23, 2022

    Dr. Brown's bottles notoriously leak if you just put the cap over the nipple. These caps seal tightly and don't allow the bottles to leak. Jan 25, 2022

  • I didn’t really find these necessary. We got them with some of our bottles and I never really used them. But I never had issues with leaking. Dec 31, 2021

    Great for traveling without spills. Also great to cap bottles when pumping at work. Dec 19, 2021

  • Loved these! They were great for capping the bottles with pumped breast milk. These caps work for Dr Browns and most any other narrow neck bottles. No leaks! Nov 25, 2021

  • these are a livesaver. the 8oz dr browns bottles wont fit in the zippered bottle pouch with all the parts on so we use the caps. plus i hate those little discs taht come with the bottle for spills Oct 25, 2021

  • Easy to use, easy to clean and fits my Medela pump jars. Oct 17, 2021

  • Buy this now! It is an absolute must have for travel and keeping in diaper bags. The lids are secure and prevent leaks. Oct 15, 2021

  • These are great to have on hand. I found them useful when sealing bottles temporarily to shake them up without spilling milk out. Sep 29, 2021

    • Wilmington, North Carolina

    Work great for storing milk! Never had any leaks with these! Sep 05, 2021

  • Life saver for formula travel! Close tight and never had an issue with leaks! These are great for shaking bottles, too, to mix formula. Apr 25, 2021

  • I use these all the time when I am pumping on the go if I do not want to freeze my milk. Then I can store in fridge and use for a bottle. Apr 09, 2021

  • These are great because dr browns leak bad. The only thing I didn’t like was having to take the inside piece out in order to get the lid to close. Apr 02, 2021

    • Pam H.

    • St. Louis , Missouri

    These are the best for using even at home. I put them on the bottles and shake before putting the vent/nipple on. Helps get the clumps of formula broken up before feeding to the baby. Mar 09, 2021

  • When my wife first got these I was so skeptical. But, as always she was right. Say goodbye to leaks in the car and the bag Feb 05, 2021

    Great for pumping directly in to bottles and the transporting home from work. Jan 18, 2021

    Very useful if you use the dr brown system. Put on this cap and when feeding time, just screw on the feeding nipple. Oct 14, 2020

  • Just to be clear the only reason they even make this product is because the bottle, even with the cap on, will leak EVERYWHERE floating around in a bag. So, it works, but just another piece to add in Oct 02, 2020

  • I used Dr Brown's bottles sometimes to pump into with my breast pump and these lids made it easy to store the milk in the same bottles instead of having to transfer them. Love these! Sep 12, 2020

  • If you plan on going out with your baby and you have dr. Browns bottles, you must get these!!! Aug 15, 2020

    Air tight and prevents leaks wonderfully. Although they do end up at the bottom of the bag or lost. Always buying more to replace Aug 11, 2020

    Dr. Brown’s bottles are a guaranteed leakfest without buying these special caps. Even after baby gave them up you could still use the bottles and these caps for any liquid storage. Worth investment. Jun 25, 2020

  • I didn’t get these right away so when I did it was an immediate help when packing multiple bottles for the day! Jun 01, 2020

  • If you use the doctor brown bottles these are a need to have. We pre measure water for formula and use these lids for the bottles. Haven’t had any issue with leaking Jan 20, 2020

  • Love these lids for storing my bottles with breast milk in the fridge instead of storing with the nipples (No cold nipples). Tight seal, great for traveling also! Jan 09, 2020

  • Necessary for mixing formula on the go without making a mess! Jan 03, 2020

    • Karen C.

    • East Taunton, Massachusetts

    I use these when making a bottle. I don’t use them to travel. It’s cleaner to shake the bottles with the caps on instead of the nipple Dec 01, 2019

  • I would use these caps to put on my doctor brown bottles to shake the formula in. Otherwise without this product, the milk spills EVERYWHERE! Nov 11, 2019

    A must have! Closes tight for traveling and allows mixing powder formula in bottle by shaking. When on the go, I store the nipple, ring, and vent in a ziploc bag. Oct 23, 2019
