The MAM starter set is a great bottle for babies suffering from excess wind. My daughter suffered with the Tommy Tippee bottles to start with, however after changing to these, her wind completely disappeared. The teat is wide enough to stop any excess wind from being swallowed and is accepted by baby very easily. The designs on bottles are also great, with lovely gender specific and neutral patterns.
The only down side is when you shake the bottle. We use these with the Tommee Tippee Prep Machine and the milk leaks almost every time we use it. Due to the bottles being self sterilising, the bottom on the bottle comes off which allows potential leaks. The milk also comes out the teat and drips down the side of the bottle, so we always have to wipe the inside before putting the lid back on.
All in all I give these bottles a 7/10 rating.
