Philips Avent Natural Baby Bottle Slow Flow Nipple, 1M+, 4pk, Flow 2, SCF652/43

Strongly suspect these are counterfeit. Significantly thinner than past avent tops (so they either changed their manufacturing or...), first ones (after raising 3 kids using these) to regularly invert, and out of the 8 purchased through Amazon, 6 tore by the top hole within a few weeks, which had never happened to any of the countless avent tops previously used.

Don’t bother buying these as they are all faulty. They constantly collapse. Awful!

I got some bottles second hand and wanted new nipples for them. These are exactly as described.

Great Product

I bought 8 of these, and 3 of them collapse when my daughter drinks bottles with them. I had to throw those 3 away so it felt bad paying all that money for 5 nipples.

My child was breast fed so when I decided to use a bottle I used avent natural bottles and nipples, he will not take any other nipple.

Excelente

Love it! Great nipples for the best bottles that my baby loves!

Good quality

I bought the #1 nipple and they work great. The two pack of #2 nipples however kept collapsing or sinking in on my baby.. I had to keep on pulling it out and putting it back in… it was so frustrating that I threw them all in the trash. What a waste of money.
