I've had issues with baby Brezza my wife doesn't even use it she makes enough bottles for the day in the morning and puts them in the fridge and in bottle warmer when needed .. the problems it does not mix great a lot of the bottles u still have to shake as some power is at bottom of bottle and my baby likes warm milk it isn't that warm to begin with even on the highest setting always reheating in the bottle warmer anyway and the taste I have tried both the brezza tastes watered down compared to the classic way. and cleaning I feel like I have to clean it every other day there's more but I stop now. overall I would rate it a 4/10 and would not recommend to anyone....
