I absolutely love this bottle. It looks great and it works well. It's one of the best baby purchases I've made. It heats up the milk fast and without the hassle of manual activation of the heat pack (it activates itself when you close the compartment). It doesn't leak and it just makes my life a lot easier when we're on the go. The thought of spending more money on a bottle was a hurdle I am glad I got over because it's totally worth it. Now that it's summer and we're out more, I bought a second one and we are set.
