(The only thing I don't know is if, since it says temperature control, the line should turn blue and white depending on whether the milk is cold or hot, because at least with my bottle it doesn't happen).

Positives: good quality plastic, nipple, does not drip and cleans easily. Negatives: unfortunately the lid does not fit with the nipple so you can't shake it! I am forced to use the coffee mixer to stir it slightly.. very inconvenient and for this reason I do not use it outside the house.

Overall, I am not satisfied at all with the company's products, but especially the bottles are the worst. With this particular one, the baby only sucks in air, if that's how anti-colic bottles are supposed to be... other companies are laughing. Not a good bottle at all, I would not recommend it at all

My baby has been very comfortable with the Nuk pacifiers because they are wide but not too big.
