I had major leaking problems with these bottles! It was extremely frustrating to wake up in the middle of the night and prepare a bottle and then have to begin to leak and start all over again! I called Playtex several times to tell them about the problem. Each time they sent me replacement bottles/parts and coupons for Playtex products. After about a month of dealing with the mess I finally called them back and told them the bottles were still leaking and that I appreciated all of their help but I would not be using their bottles any more. I wish I would have known before I had bought the whole set of bottles. Hopefully the word will get out there so other moms don't waste their time and money!

I hear what you guys are saying about making sure it is tight enough.. but we have had the opposite problem we were having to unscrew ours because when we tightened them all the way they leaked. The bottle would be a good bottle if the thing in the bottom would hold up. They are just not worth the time if you can find a good bottle you dont have to be thinking about all the time, expecially when you are in the car or on the go!

I HATED these bottles. It didn't help we didn't read the instructions properly before using, but who would have thought you needed to read instructions before using a baby bottle! The vent at the bottom was not letting air flow properly, my son literally fussed and cried for 20 mins before we realized he wasn't getting any milk; and then after re-reading the instructions, they still didn't work. I ended up returning them for Avent bottles which are FANTASTIC!

We did not like this bottle. It leaked, yes even if the gaskets were straight and tight. It was just a really bad experience for us.

Do not like them! There is so many peices to one bottle, and when a baby is screaming it takes way to long to clean!

There are to many pieces to this bottle. It did not help with my sons colic or spitting up either. Also my son did not like the shape of the nipple. All things considered I don't think this is a good bottle.

I didn't like these so we switched to the drop ins.

The bottles are HUGE. My 4.5 month old daughter hates all bottles, including this one. But most bottles come in smaller size options. This one requires us to fill it up more, which is a waste. (I had to buy out all of Babies R Us bottles to figure out which bottle she hated the least.)

Used these for my son....terrible!

I Hated these bottles so much because although they did help my son with colics every time i had to male sure it was put together right because otherwise my son would get soaked in milk.

I never liked these bottles! They always leaked everywhere.

To be completely honest,I hate these bottles. They leak everywhere,they're a pain to put together & after my son used them he would not burp (i tried everything) & ended up whaling for about an hour or so afterward.

Leaky bottles I loved that the bottles were angled and super easy to hold. But after a few uses they started leaking everywhere and the slowest flow nipple was so fast my son choked. The numbers started rubbing of the sides too.

Not worth it They work alright but they leak a little when you shake them. I also hated having to completely disassemble the bottle for cleaning. It didn't reduce the acid reflux which was my main goal with the purchase. When he was able to hold the bottle it was a weird angle and he had issues.

Not worth the price They leaked Everytime I used them. I ended up buying cheaper bottle that worked 10 times better.
