“I just received my Traveler yesterday but I love it already! I love that it’s leakproof, that it has a see-through top, that the straw folds down and out of the way, and that it’s 40oz. Like I said, I only received it yesterday… but I put ice in it at about 7pm yesterday evening and there is still plenty of ice now at almost 4pm the next day (that is after I’ve added water twice also). I would definitely recommend!”
