We loves these caps. It makes it way easier to shake a bottle to mix it. And it is also great to transport water when going out.

Before I had these I would shake the bottle with formula and not only was it still clumpy but the formula went back into the resevoir and leaked from the pressure. After I got these I would prepare bottles ahead of time with the dr browns formula pitcher (which is Amazing!) and not have to worry about clumps! And also if you are traveling they are convient for shaking the formula in the bottle.

These are really useful for getting out of the house but above all I found them useful for shaking/mixing the formula, just snap it on the bottle, shake and it helps with no mess.

These caps are great for the ever leaking Dr. Brown’s bottles. I don’t know why I waited so long to buy these! My only negative comment about these is that they don’t fit over the tan inserts that sit in the mouth of the bottle. You have to remember to put those and the blue resevoirs in your bag seperately, which I have a tendency to forget. This is just a personal annoyance though!

I wish the bottles came with these caps. They’re great for travel and are a necessity when you’re needing to shake up formula in the bottles.

As a mom on the run and using the safe Dr. Browns bottles these came in very handy.Work perfect. Never had any leaks.

Fits Dr. Brown’s bottles, as well as most standard sized bottles. Screws on tight, and I never had to worry about it leaking while these were on. Cleans easily.

I really wanted to love these caps and they are good for storing premade formula without wasting a nipple and cap. However, I found that the caps can leak if the bottles get tipped over in a diaper bag or the like. I imagine you could screw them tight enough to prevent this, but at that point I would have trouble getting the cap back off. I would have given this 5 stars if it had a washer in the cap to prevent leaks but I imagine they would have cost more. That being said, they are wonderful for storage in your fridge or other place where you know they won’t tip over.

Got these thinking they would fit the Born Free wide mouth bottles and the do! very happy with them, if you are looking for lids for your Born Free bottles these will work for ya!

We actually threw the ones that came with the bottle out thinking we would not use them. We were wrong, these replaced them and they work well particularly for helping to mix formula.

We’ve found that when heating a Dr. Brown’s bottle in an electric bottle warmer, it will overflow if you already have all the bottle parts assembled. But if you use these lids to cap the bottle, then it heats perfectly. And these are great for storing the bottles in the fridge.

These are great for mixing bottles and for traveling with a bottle. They screw on tightly and I haven’t had any leaks when mixing the formula or when thrown in the diaper bag.

I use this caps to avoid leaking when I am shaking and preparing the formula in the bottles and keep in the fridge.

Does not leak. For the high price of Dr. Brown’s bottles, you’d think they would include caps with the bottle purchase. When my babies outgrew the 120ml bottles, I started using those bottles for milk storage, thus I needed these caps.

Fits my Dr. Brown’s wide neck bottles perfectly! I love it, because it’s great for storing formula in the fridge. When trying to shake the formula powder with water in the Dr. Brown’s bottle, it leaks, but when I use this, I get no leaks. It’s great for traveling. Just put the cap on and bring the other parts with you, and you’re good to go!

Getting these caps was just helpful for travel. I keep the other parts separate for later use so when going through TSA much easier to just open lid than all other pieces.

Our bottles came with a couple of these, but we needed more for traveling. They arrived quickly in great condition.

My born free glass bottles don’t have caps. These Dr. Brown caps fit perfectly! Now I can use my BF glass bottles to store breastmilk in the fridge without worrying being contaminated by the smell of other food

A must have for storing premixed formula in Dr. Brown’s bottles.PROS:Easy to clean.Durable. It will hold up with regular cleaning on hot water. It held up well when we first sterilize it using Dr. Brown’s microwave sterilizer for 5 minutes in the microwave.CONS:I wish each Dr. Brown bottle came with one of this.
