The “Texas Hold'Em” singer keeps her Contigo water bottle close (even when is on stage), but he is far from the only buyer impressed by the brand. As one Walmart shopper wrote, “This glass is just the right size to hold my cold coffee (from home) all day! It doesn't really fit into my travel mug spot in the car, but it stays there without falling out, so that's a win!”

One buyer compared the Contigo to another popular tumbler that keeps drinks hot and cold for hours at a time. “This cup is as good as a Stanley at keeping my coffee hot,” reads the review. “I bought this for my fiance who is a truck driver,” noted the buyer. “He likes that it fits in his cup holders and drinks stay cold for hours.”
