I was honestly pretty skeptical at first and figured I’d just return it if it didn’t work. But we had a trip coming up with our baby, so I took a chance and I’m so glad I did. This little warmer was quite useful. As it was type C, we could easily charge it, we never had to panic about warming a bottle, and it barely took up any space in my bag. Traveling with a baby is usually chaotic, but this made feeding part at least feel calm and stress-free.
