When bottle, sold in sets of two, my daughter loves, and I no longer swears by deeming this brand worldwide.
Build quality, durability, easy maintenance, these bottles have it all. I turn bottles a competitive product for after only 3 passages sterilizer, pacifiers were any curl !!! AVENT them, do not move a muscle :)
I noticed that my baby had less colic, their system is so effective, that are not hype.
Finally talk about money, they are expensive, okay ... but the competitor brand baby bottles that have landed in the trash are a mere 3 euros cheaper ... I think that it is money well spent. they are cheaper on the Philips site, but with postage, the price exceeds that applied by amazon, so I still win.
