These bottles leak every use. We have two so am sure it is not a malfunction, as both leak. We are not overfilling and kid is always on tight. I would not recommend this particular style of Doctor Browns.

We were recommended by health professionals to try Dr Brown's bottles for our very colicky baby who had a lot of wind issues birth- 18 months ish. We have found them to be very ineffective and in our honest opinion a waste of money. They had no effect whatsoever. We also found they continually leaked through the seal and were very hard to clean. Each to their own, but I definitely would not use again in future.

These bottles are the worst bottles on the market. Not only do they leak like a sieve they also have a million parts that need washing. If you want your baby to stay dry during feeding then look elsewhere.

For the price of the bottles it’s not worth it. My child is 7 months now and I’ve changed teats and paid extra money have everything dr Brown and the green & blue stems inside stretch and bend and the circle thing under the lid also stretches my bottles all leak milk and water every time all over my child and me so disappointing. Also hard to clean the stems and inside of the circle under the lid. Have purchased the $10 three pack of bottles from tommee tippee for 1 week now and not 1 leak.

We purchased 6 bottles for our son. These bottles were great for the first month. Now the green internal component is loose and causes the bottles to leak. It makes my son wet and also myself.

I’m very disappointed in the quality of this product. There are much cheaper options on the market which don’t receive anywhere near as many complaints.

I will be advising other people on various platforms of the quality of your product. Parents in various Mum clubs on all social media need to be informed before they outlay good money for a faulty product. If it was 1 bottle I could accept it but it’s not.

So frustrating trying to tamper with these bottles to get them to function properly don't shake them cause thtney are actually designed to leak the milk out of the collar if milk gets down the vent. Very fussy on if it's too tight or too loose of you want baby's milk to be warm forget it cause it can't handle the pressure from the warmth, you losses the collar to get the teat to flow and they Leak I want a refund but jot sure if they offer this. Even after trying to sort out resolve withth the company to no avail they leak.

The bottles leak EVERY single time with the straw insert inside. Each time the bottle leaked we always had to open the cap and tighten it back on even though it is already tightened on in the first place. Very frustrating particularly when you have a hungry screaming baby !!! We had to use an extra towel underneath the bottle so it wouldn’t leak on baby and wet his clothes and kept a finger underneath the cap while feeding to catch the leaks before it leaked out. If the bottle tips over for just a few seconds milk will leak everywhere too.

These bottles are terrible. They leak no matter what you do to try and stop it. Keep it below Max fill line, they leak. Shake the bottle, they leak. Valve in, they leak. Valve out, they leak. Feeding baby, they leak. Lid on tight, they leak. Lid not so tight, they leak. An absolute nightmare!

These bottles are terrible. They leak so bad even when the lid is on super tight which is then so hard to get off. My husband rang to complain and they were totally not interested. Look for another brand as these bottles are useless. All you’ll be doing is wiping up spilt milk off the floor.

I bought the Dr Brown wide neck bottle set as my baby had reflux. Although my baby did burp less but the leaking was really bad. We made sure to not fill the bottle above the max line but when your baby is screaming for milk the last thing you want is to have expressed breastmilk leaking out making your baby cry even more and wasting your breastmilk that was already difficult to express! Do not recommend this product at all.

It's frustrating that the bottles leak everytime. Changing the brand to something else. I am sick of the bottles leaks. Its spilling so badly that you even need to change the babies clothes. It worked fine in the beginning but now i hate it. I have 4 bottles and all of them does the same.

Bottles really are a great concept but after 1 week of using daily started to leak. I did everything recommended to stop the leaking but did not help. They are a waste of money in my opinion. Went back to Avent bottles as they do not leak in the slightest.

I lost so much expressed milk because of those bottles its so frustrating, they leak if you are trying to warm up the milk and if straw comes off with moving the bottle, with time to get a straw part will not sit on bottles properly and will keep coming off, very frustrated and i don't like them.

I bought these bottles as I'd read great reviews about them helping with wind/colic. No idea if that's actually true because I've only used them three times and I'm ready to throw them away.

If you shake them to mix formula, they leak. If you heat them in a bottle warmer, they leak. If you tilt them to test milk temperature, they leak. They even leaked all over my baby during feeding. After two washes (with the included mini bottle brush) the nipple went from low-flow to no-flow. Exactly what I want to find out with a hungry infant waiting to be fed.

Don't waste your money on these overpriced, cumbersome bottles. I'm going back to my Tommee Tippees.

We bought 2 of the Dr Browns Options wide neck bottles and honestly it was the biggest waste of money. The biggest complaint is it just leaks everywhere! No matter how much I tighten all the parts it still leaks everywhere. It's just terrible you end up with more milk on bubs clothes/bibs or your hands then what gets consumed.
Don't buy the options bottles!
