First of all, it is the most affordable if we are to compare the three, in fact, it is probably the cheapest baby bottle warmer we have ever came across in the market. It doesn't discount on its quality and functionality though.
Rather, it is a 2-in-1 bottle warmer - incorporating both warming and sterilizing functions in one small unit. Yep, it couldn't be any more value for money than this.
Let's start with its warming function, our main objective first.
As pictured left, you can see that The First Years bottle warmer is a rather small and compact unit.
A water vial sits in front of the bottle compartment and this, despite being such a simple addition, is all that makes a difference.
You see, more often than not, parents find it a rather tricky job to pour water precisely into compartment without creating some sort of a mess.
The water vial solves this once and for all and what's best, is that a water measuring guide is provided as well.
This tells you exactly just how much water is required for the different types of milk (breast or formula), the different volume/bottle size you're using as well as for baby food.
The vial itself has minute markings so all you have to do is just measure accordingly and you'll be able to warm your content to just the right temperature. Note that this is just a recommended duration, at the end of the day, you should go according to your baby's preference.
One more advantage of having a water vial is that you can prefill it to the desired amount and store it in the warmer so that you don't need to measure in the middle of the night.
To start heating, just pour the water into the chamber and press (the only) button and the unit will warm your breastmilk / formula in just minutes. When you see the light goes off, it means your milk is ready and the device will automatically shut itself off.
When it comes to its sanitizing feature, you will have to use the basket provided that comes with a lid as pictured left.
As you can see, the basket is not very big which means you won't be able to sterilize bigger items, but a few pacifiers is more than sufficient a capacity.
Designed to hold most baby bottle styles that parents already own, The First Years 2-in-1 Bottle Warmer is one of the most versatile, fitting straight, angled, narrow, wide-necked and even disposable bottles.
Overall, if you do not want to spend too much on a bottle warmer, yet does not want to compromise on quality (well, that's most of us, isn't it?), then The First Years 2-in-1 Bottle Warmer is the best baby milk warmer for you.
It did not become a best seller for no reason!
