Contains BPA, don't buy!! 
2008-08-25
These bottles contain BPA, a chemical that mimics hormones and can disrupt develop, especially in infants. We had these bottles and have replaced them with glass bottles and stainless steel sippy cups. Avent pacifiers also contain BPA, steer clear of these products!!
Contains BPA -- TOXIC Substance!!!! 2008-08-11
BPA, a synthetic sex hormone that mimics estrogen, is used to make hard polycarbonate plastic. Ninety-five percent of all baby bottles on the market are made with bisphenol A. The results of the U.S. study show that, when new bottles are heated, those manufactured by Avent, Evenflo, Dr. Brown's and Disney/First Years leached between 4.7 - 8.3 parts per billion of bisphenol A.
Do your research, moms! There are lots of bottles out there that don't contain BPA. Trusted brands like Green to grow, Born Free, Adiri, and Thinkbaby.
BPA - Bad plastic 2008-07-08
Unfortunately, these bottles contain BPA that can leak into your baby's milk if you heat them. When I found out we immediately switched to Evenflo glass bottles.
Otherwise I actually liked the bottles. I liked the wide opening that allows for easy cleaning. I hardly had any leaks, only sometimes when I didn't screw the lid on just right or when the nipple wasn't pulled all the way through.
What I didn't like was that they are not compatible with any other breast pump except Avent breast pumps. However, Avent breast pumps never worked for me, so that was a major bummer. I think someone makes conversion kits for Avent bottles so they might fit onto a standard bottle sized breast pump.
Why can't they make these in glass or at least in plastic without BPA?
LEAK! 2008-07-07
These bottles are horrible! They leak no matter how much or little you tighten the ring.
Avent system: excellent quality bottles and nipples, some concern about BPA with heating 
2008-06-07
Despite the concerns about BPA we are using these bottles for our daughter, and using canned formula to supplement breastfeeding. The concern with BPA seems to be heightened when the bottles are washed with hot water, or sterilized at hot temperatures. We bought this sterilizer, but have stopped using it. However, we still use the dishwasher, which is fairly hot. I am keeping an eye on Avent's statements:

We keep using them because they seem to be really excellent bottles and nipples, she feeds easily and doesn't get a whole lot of gas. The nipples are designed so that you can graduate her to faster flow nipples as she gets bigger. We are hoping that the BPA concerns will turn out to be unwarranted.
BPA 2008-05-23
The most natural choice for bottle feeding in a convenient set! With two sizes of bottles, two pacifiers and a bottle brush, you have everything you need to get started. The Natural Feeding Bottle promotes healthy, active feeding and is the only bottle clinically shown to reduce colic. The nipple features a built-in valve that works with baby's natural feeding rhythm so baby can control the flow of milk, which can help reduce risk of overeating and spit-up. It also keeps air out of baby's tummy, resulting in less colic and less gas after feeding. The soft, naturally shaped nipple encourages proper latch-on, making it easier for baby to switch between breast and bottle feeding. The AVENT Natural Feeding Bottle is ultra hygienic, convenient and has no small parts to clean or assemble.
Avent makes toxic products. Do not patronize. 2008-05-20
Do not patronize products from Avent because Avent is one of the most vocal pro-BPA manufacturers because of its functionality, regardless if it poisons our children. Buy from Playtex or Born free. They are more responsible. Dont buy this garbage. I am a doctor and I bought these bottles at first because of the marketing, I threw them away when I found out they are poisoning my child.
No where near as good as Ventaire 
2008-05-01
These bottles have been used in the UK for years. I bought one and my husband made the passing remark, Oh, everyone uses these back home (him being British). When shopping for bottles while I was pregnant, we'd bought the Newborn set of Playtex drop-ins, a gift-set of the Ventaires and it wasn't until my son was about 2 weeks old that I bought one of these.
My son is now 11 weeks old and I can honestly say that I only use this bottle as a last resort. My husband and I, both have had problems with leaks, though not terribly so. It isn't due to the lack of following instructions, either. As I said, these are the most common ones my husband has used in England and he's very familiar with them.
The main reason I don't like these bottles is that the vents are on the nipple ring, allowing the air to pass through and aerate the formula, contributing to gas, which is thought to be the main cause of colic. The slower flow nipple is still too fast for my baby, even with him being a big eater. He has trouble controlling the flow on this bottle, that's where he gets messy, stuggles to feed, gets frustrated and then refuses the bottle. The ventaire bottles allow the natural vacuum in the bottle to suck air in through the bottle of the bottle via a thin silicone membrane on the vent rings. No air enters the formula and bubbles stay far away from baby's tummy.
Like others, I too, have found that the nipple isn't helpful to a breast/bottle fed baby. The shape looks like it would be helpful with latch as the pacakge suggests, but, really, any wide neck bottle provides a bit of latch help just as much. The silicone on these is just too thick and firm.
If you do want to try these bottles, I suggest putting in an anti-gas agent, like simethicone (Mylicon, I use the Wal-mart brand... much more affordable), into the formula before shaking. This will greatly reduce the retention of bubbles in the bottle, and burp your baby well. I also suggest getting the nipple slower than what the package suggests.
Just remember, bubbles going through the formula means bubbles in the tummy, and bubbles in the tummy means gas and discomfort.
Just Ok 2008-04-27
I am not impressed by these bottles. Yeah they work and I guess get the job done. However, they DO leak and are not breastfed baby compatible no moatter how they are advertised. My son will drink from them when he HAS too but never is happy afterwards due to the gas it causes in him. I am not looking for a better option. I am glad they were a gift and I did not spend any money on them.
Contain BPA 
2008-04-23
I'm a little concerned that this product showed up on a list on Amazon.com when I searched BPA-free bottles. I've used Avent bottles with both my kids, but now I am in the process of switching to something BPA-free. As I was looking for options, I searched Amazon.com and Avent came up as an option. These bottles contain BPA. I think this is misleading potential buyers!!
