At first, I thought it wasn't working well.
First, set it to the maximum temperature of 55 degrees, connect the power bank, and leave it for about an hour or an hour and a half, and it will get just right warm! ! Since it's the season for fresh milk right now, I turn it on at home before going to Munsan, put it in my bag, and as soon as I finish my Munsan class, I take it out and the milk is super warm!! It's easy to feed the baby and it's really light and convenient!! It's urgent to spend an hour and then an hour and a half; it's a bit of a flaw in modern society! You can reduce your luggage! Haha, I can't believe it's this good for this price! I'm extremely satisfied. It's become an essential item in my wardrobe these days!! !
