I have had both the Baby Breeza Formula Pro Advance and I know use the Baby Breeza Formula Pro Mini. I cannot recommend this product enough, it saves me from a tantrum meltdown everytime baby is hungry, conserved formula with its exact amount dispensing and always the right temp for baby. Baby has minimal gas and colic thanks to Baby breeza combined with their anti-colic baby bottle (not by Baby Breeza). If you're a mom on the fence, it's worth the investment!
