I bought it when my son was put into hospital and I found it worked really well and I had no issues with it - took about 3/4 mins to heat up a 6oz bottle and we still use it when we are out and about
I bought it when I used to travel a lot and it’s 100% worth it! It does take a couple minutes to warm up and I did have to swoosh the milk around so it’d warm up evenly but it’s so convenient! You can use it at home but this is more for like on the go since it does take a couple minutes. A regular bottle warmer or microwave is a lot faster.
i’d also like to know, i didn’t even know they had a bottle warmer. the one i got sucks
