## Customer Reviews

### ⭐⭐⭐⭐⭐ Get the Rainbow color, the perfect
*by J***Y on June 28, 2025*

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.

### ⭐⭐⭐⭐⭐ The Beast is quite beastly.
*by J***E on May 26, 2021*

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.

### ⭐⭐⭐⭐⭐ Quality and comfort
*by M***S on July 13, 2025*

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.
