  • Get the Rainbow color, the perfect
Size: 20 Ounces Color: Rainbow
Why did you pick this product vs others?: This is the right size for a large cup of coffee (20oz), starts my day right. The multicolor (rainbow color) exterior is phenomenal and picks my mood up. The base is tapered down, should fit any cup holder. This is made by a family owned business (the Greens) with high quality steel, well insulated, keeps the coffee hot. The inside of the cup somehow cleans up better than other cups I have had cleaning up quick with no coffee stain. Comes with a lid, straws, and a straw cleaner brush. Best and most enjoyable I have ever owned. ... show more

  • The Beast is quite beastly.
Size: 30 Ounces Color: Orange
I purchased both the Beast and the Yeti in the 30 oz. size. So far I use these for ice water only. The Yeti was only ten dollars more than the Beast, so I figured I would try them both and see if they are equivalent. I filled both of them at 10 AM with ice (small solid cone shaped) to the halfway mark. I then filled them the rest of the way to about a half-inch below the brim of the cup with water from the water cooler. During the day, I drank and refilled the cups, with only chilled water, four more times. By 10 PM, I still had plenty of ice in the cups. Before bed I filled the cup one more time to see if the remaining ice would last over night. It did in both cups. The room temperature was seventy degrees for the test and all water refills came from a water cooler. The ice in the 30 oz Yeti lasted twenty three hours and the ice in the Beast lasted twenty seven and a half hours, pretty impressive for both. I like the newer flip up, snap down lid on the Beast better than the Yeti's magnetic slide lid. Both are easy to clean, but the Beast lid, when snapped completely down, does not leak for me at all. I held a full cup of water and ice horizontal and then upside down. Not even a drop came out. For those that say the flip lid leaks, make sure you have it snapped down all the way. It can take a little effort. You should hear it snap into place. You know it is closed all the way, if you need two hands to open it. I like the Beast lid so much, that I replaced my Yeti lid with one. It matched my black Yeti perfectly and had a no leak fit. The Yeti magnetic slide lid is good, but if the cup falls over or if bouncing around in a vehicle, there is a little fluid that can seep out of the opening. Also, the Yeti lid will only fit the slim stainless straw and not the larger smoothie straw. The Beast lid accommodates them both. The Yeti 30 oz sells for anywhere from ten dollars or more compared to the 30 oz Beast. I do not know why some Yeti finishes are so ridiculously priced. I purchased the black Yeti and the orange Beast. As you can see from above, the Beast is as good or even slightly better in preserving the ice, under the same conditions, as the Yeti. Warranty period, five years for the Yeti, lifetime for the Beast. Only time will tell on this issue. The only difference I could visibly see, is that the Beast has a larger base then the Yeti. The Yeti fit perfectly in my car cup holder, the Beast did not. I decided to keep them both because they both look good to me and have a really hard finish. I use the Yeti in the car to travel etc. and the Beast around the house. For only a ten dollar difference I figured why not. If you get a Yeti, check out the You Tube videos on how to spot a counterfeit Yeti. Apparently, some of the Yeti's out there are counterfeit and do not keep things cold for more than a couple of hours. I did check mine out before the return period closed and it is in fact the real deal. Hope this helps. ... show more

  • Quality and comfort
Size: 42 Ounces Color: Stormy Sky Blue
Very nice quality cup, fit well in to car cupholders. Drink stayed chilled even on a hot beach. Did not leak from the lid or anything. Great pricing too, and seems more durable than the current popular similar name brand item.

  • Works great, fits perfectly in car cupholders, excellent finish and colors….and a great name!!
Size: 20 Ounces Color: Lemon
Great colors (I ordered the yellow and Army green) and the finish is perfect! The insulation works great! The other day I poured my coffee at 8am and didn’t get back to it until 11am and it was still nice and toasty. And that time in between included a car ride and several meetings and I was impressed when I found it to be nice snd warm. I will totally order this again! ... show more

  • works well
Size: 40 Ounces Color: Stainless Steel
The tumbler holds ice, without melting, for at least 8 hours. The seamless stainless steel construction makes the tumbler easy to clean. The top only has only one opening for both drinking directly and using a straw so if the tumbler is knocked over while using a straw it will lose water. The tumbler has a small bottom to fit cup holders but it's 40 ounce capacity means a large upper section That shape is no problem unless you're a small child or an adult with infirm hands. I'm pleased with quality of the mug. ... show more

  • Great Product
Size: 40 Ounces Color: Army Green
Perfect size and design for me. Keeps cold cold and hot hot. If you have arthritis in your hands, the handle provides a grip that makes it much easier to use for extended periods of time than trying to stretch your hands around a large handle-less container. The way the lid/cap is made is versatile: use with or without the provided metal straws. ... show more
