First I would like to tell you that you should look some important factor while purchasing best baby brezza bottle warmer that is size matters a lot but mostly used size is 4 or 8 ounces. On the other hand, speed control also plays an important role in bottle warmer you should pick that one which can heat up your milk even in no time that will be your best friend.
Furthermore, also observe the material inside of bottle warmer that comes in different materials because warming up the milk must require different time and temperature.
As far as the cleanliness is concerned, I always say that we do not need such baby products that need rocket science in order to keep that clean as simple wash in dishwasher is enough.
Here I would recommend another non-portable bottle warmer that is from Baby Brezza. As it comes with two warming functions or features and those are: one for formula milk and the other one is for breast milk. As the matter of fact, the difference in between two is first heating is slow in order o preserve the nutrients. And on the other hand second one option is for quick heating.
The great point is that you can easily operate this bottle warmer through the mobile app that is activated through your Bluetooth. That allows to heat up your milk by just taping your fingers as well!
It helps a lot in heating milk to your desired temperature, and easy to use, it also suitable to heat up the baby food and even can easily hold up any bottle.
On the other hand, it is expensive and boring to use without the phone app. But it got a lot of fame and even got 5stars rating and comes in the quality of A+. as you know that quality matters a lot and all depends on its integrity which is easily judged by the durability that this can be sustained even after a lot of use. Moreover, I would like to say that it does not offers such great quality and integrity but it values to you and to your money as well and this is the main reason that it got 5star rating in the market.
