Massive Capacity, All-Day Chill, and Built Like a Tank

I picked up the Beast 50 oz Tumbler because I was tired of constant refills—and this thing delivers. It holds a serious amount of liquid (coffee, water, smoothies—you name it), and the double-wall vacuum insulation keeps drinks cold for hours, even in the summer heat. Hot drinks stay warm too, without the outside getting too hot to hold.The stainless steel build feels solid and durable, and the lid seals tight without leaks. It fits in most large cup holders (though not all), and the included straw and brush are a nice bonus. Whether I’m working, driving, or just trying to stay hydrated, this tumbler keeps up.If you’re looking for a no-nonsense, high-capacity tumbler that actually does what it promises, the Beast lives up to its name.

Better than Yeti

I have several Breast tumblers and I absolutely love them. Drinks stay cold and iced for hrs. Lid is definitely leak proof. I love how the handle is attached to the cup and not removable.

Everything I was looking for!

I was impressed at the quality for such a cheap price. This is a large size, handle, cool rainbow metallic color, great lid thats a screw top with a flip top and air hole making it easier to sip. Keeps my tea hot for hours. Very nicely packaged and I even got a coupon to use on a future purchase. I will be buying more. The Beast is a great purchase!

Nice but not perfect without a built-in handle.

This is a quality product. Lots of nice colors to pick from. Fits in our car's cup holder. Keeps hot drinks hot and cold things cold. Dishwasher safe. Fits under our frig's water dispenser. But it does not have a handle. A major flaw for our family. So, we bought the handle that you can slip on to it. Too bad that it does not work. It slips down. Not what you want when you go to grab it out of the cup holder in the car. So, the tumbler and the added handle go back. Reason for a star missing. The hunt begins again for all perfect water/coffee tumbler for our family.

HOT, COLD, AWESOME!

These cups are awesome!! I love the colors, and I love the way they keep drinks hot and/or cold! We have seven of them in different colors, and we have had our original two for nearly 5 years. They are very large for a woman's hands, so the handle that is sold separately is definitely recommended. They offer a 30-ounce size, which is much easier for women to hold. They are steel, so they don't rust, and the colors are made with a vinyl covering. We have found these cups to do an excellent job at holding the temperature of any drink you put in them, and they will keep cold drinks cold even when left in a hot car for hours. Each cup comes with metal straws in two sizes and a brush for cleaning inside the straws. We wash them in the top rack of the dishwasher and have had excellent luck with that. These cups are strongly recommended.
