My husband and I have 3 week old twin boys, so I don't need to tell you we needed stuff to make our lives a lot easier. We ended up buying 2 they were so useful, so when the boys are both fussing, they eat at the same time. Doesn't take too long to get hot, but I find some times it's hit and miss with the temperature. You really have to make sure you're putting the right amount of water in for the perfect temperature, which is hard to do at 3 in the morning when you're exhausted. But all in all I love this product!
