Bests & Worsts Reviews from Amazon

My kid relies on a specialized formula to survive, and the search for a good leak-proof cup has been difficult. He chews through all of the soft spouts, rendering most cups unusable (with the exception of Camelbaks that have replacement spouts). But this is it. This is the one. I can shake the cup to mix the formula without it splashing all over the place, and the hard spout guarantees a longer life for the cup in this household. I'll definitely be purchasing more!
