This was given to my little guy (4 yrs. old) and he uses it all day-long. He calls it his "puppy cup" and we cannot leave home without it. It has been wonderful to take along to the park or out running errands. It fits in his car-seat cup-holder, in my diaper bag, and stays cold all night---so it's great for when he wakes up wanting a drink since we leave it next to his bed.
These are great! If you have kids or NEED A FUN GIFT that is actually USEFUL this is it! It's makes a GREAT Mother's Day gift for the harried mom who wants to take her adult beverage out of the restaurant with her screaming children.
My daughter absolutely loves this cup!
I have bought 4 of these tumblers for gifts. They are wonderful. Very durable and did I mention how adorable they are as well!!!
