Something I wish someone had told me sooner: the Tommee Tippee “anti-colic” feature is a bit like promising your shirt will never get stained just because you bought stain remover-it works for some, but don’t expect miracles. The pieces do come apart and go back together pretty quickly, even when you’re sleep-deprived and holding them at 3am with one eye open. However, if you’re looking for compatibility with pumps, you might find yourself inventing new cuss words; Tommee Tippee just isn’t very universal unless you want to stock up on their proprietary adapters.
Leaking? It’ll happen if you don’t snap the lid on like you’re trying to beat a world record. As for baby preference, mine switched from breast to Tommee Tippee without sending me to the baby bottle Hall of Shame, but I know others have had pickier customers. In sum: decent overall, just be ready to embrace the quirks!
