“My first ever hydrojug and I absolute love the look of it! I’m not sure if it is just the type of cup, but I’ve had some insulated tumblers that hold ice for 24 hours or longer. But I can fill my cup with ice in the morning and I can’t get through a 12 hour with ice still in my cup. I’m not sure how long it is supposed to hold ice for, but mine is completed melted before the end of my day. Like I said, I love the cup and I’m not trying to complain! I just wished it held ice a little longer”
