I really was loving the cups so much, even my children were loving them, but as soon as we had them for about less than 30 hours , the tip in the top of the silicone straw, was already leaking out. I’m really not a fan of cups that leak, so we won’t really use them as regulars cups now. Also I’m still waiting on another cup, it was for my mom. I received two children’s cups, but still awaiting one more. Thank you!
