"They are okay. "
My daughter liked bottles. We liked them, too, but they did leak sometimes, and they also have BPA in them. If I'm going to pay this much for any bottles, I want them to be BPA-free, or at least not leak. We just got Sassy Mam bottles which are almost the same price and BPA free, plus good for colicky symptoms as well. I also love the Playtex ventaire advanced bottles which are really good quality bottles and are also for less fussing, spitting up, gas, etc. and my daughter enjoys them too, but they are not BPA free either. We keep these only for back up bottles now. The avent bottles- we wound up tossing all of them completely. not really worth the price.

"Leaky Bottles"
I first used these bottles when my son was born two years ago. Like some of the other reviewers, I found that these bottles leaked. I had to tighten/untighten them all the time and although not all the seals leaked, many of them did. Now, with the BPA issue, I'm not using them at all with my new baby. I've purchased a different brand that doesn't leak, doesn't have BPA, and is also less expensive.

"stay away"
Stay as far away from Avent feeding bottles as you can. This product is total junk, the bottles leak all the time. We have tried many, different sizes, different nipples, purchased at different stores and different times. They are all the same, they leak from under the lid no matter how tight you screw it on. Complete garbage.

"They leak "
I got these bottles as a gift and since bottles are expensive, I used them. I had no problems in general, my baby used them fine from the time she was 5 weeks old. I'm just weaning her now at 13 mos. The major complaint I have about these is that they leak around the rim like crazy. Sometimes you have to unsrew it and put it back on two or three times before you can keep them from running all over. And, no, it's not just one. All of them did it.

"not sure why anyone would buy these"
Is there a rating below one star?

First of all, we bought these before we learned about BPA. Our pediatrician told us about the fact that BPA is a neurotoxin that stunts brain development, among other nasty side effects.

So first of all, they aren't safe. So why buy them?

But if you don't buy the BPA stuff, there are a ton of other reasons not to buy them. Number one, they are extremely expensive for what you get. You can get twice as many Evenflo glass bottles for the same price as this three pack. So they are unsafe AND twice as expensive.

Then just to add insult to injury, the nipple is designed very poorly and makes it incredibly difficult for an infant to latch on. They cannot create the vacuum they need to get the milk out. Once there is only about an ounce of milk left in the bottle, my son could suck for an hour and not get the last ounce out. It was very frustrating for him and for me. I got to the point where I would express that last ounce of milk out for him to get it, basically spraying it in his mouth, which he didn't really like either.

So in summary, this bottle could not be any worse. And sorry, but there are better, cheaper, and safer alternatives that work better. Yet these keep selling. Makes you wonder whether Avent employees have written up these positive reviews.
