For my baby (6wks), I have found they are not good, the smallest/slowest teet is way too fast flowing and my baby swallows and chokes on them. At 6 weeks my baby does a lot better with the Mam bottles but I'd try Tommee Tippee again when she's older. If your baby is older they may be good.
Personally I just think no bottle is going to stop it they are all anti colic just a marketing tactic x
