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.

Beast vs. Stanley
I canโt say enough about this cup. I bought it January 2023 and itโs January 2026 now. I got a Stanley for my birthday as a gift so I compared the two. My $30 dollar rainbow beast to the $50 Stanley glitter bomb. The quality is absolutely amazing on both cups my drink is cold and still has ice after 14 hours I havenโt tested for hot in my 40oz but I have the 20 and it keeps my coffee hot through lunch. I love the design and colors offered on beast the rainbow is my favorite. The beast tumbler is lighter than the Stanley and I prefer the removable cuff handle that I have for the beast tumbler. Car cup holder though the Stanley was a better fit but itโs really tall. My beast fits in the cupholder if I had the coaster in the bottom of the cup holder so eh not a big deal. The one thing I like the Stanley over the beast is the lid. The beast has an opening so that you can use it with or without a straw so bugs can get in hair/dust while the Stanley is closed top 100%. I love both cups but for quality and bang for your buck beast is the winner.

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!

Perfect for the pool!
This tumbler is great. We had We bought 2 of these for the coming summer days outside or at the pool but decided to try them out for game night & they worked really well. They held ice for a couple days & kept our drinks nice & cold. when we went to clean them 2 days later. I would definitely buy again!

Great product but...
The reason its getting 4 stars isn't because its a bad product. Its actually really good. Keeps things nice and hot for long periods and cold even longer. The reason for 4 stars is the lid. The lid leaks and is not leak proof. If the lod was leak proof and worked like it should it would have been a 5 star. Still would recommend this to people as it is a solid product.

Great buy! Great quality!
Lost my YETI last month, and I decided to go with a less expensive replacement. This 20 oz. insulates my ice water just as well as the YETI. Came with two metal strawsโ one straight, one bentโ and a straw brush. FlipTop is fine, but I did order a magnetic slide top like my YETI had; two pack on Amazon was under $10. No leaks. Fits my hand nicely and lightweight. Really pleased with the quality! The frosted black is really nice. ๐

Most durable tumbler out there
This is one of the best tumblers on the market. I had others with handles that easily broke or became loose with no way to tighten them or re-attach them. The handles on this tumbler are welded to the tumbler, so they are all one piece. The size (42oz.) might seem over-whelming but, it will still fit in the typical auto cup-holder. Drinks stay cold or hot as they were meant to be for more hours than expected. I hope to get many months/years of use from this tumbler. I bought a 2nd one as well.

Keeps water cold for a very long time, lid seal is tight, versatile (swig or straw), easy to clean
I am typical: I have to have my large tumbler with me at all times. I had purchased this same model a few years ago, but I dropped it on the driveway last week, and the plastic flip closure on the lid broke. I did find a replacement lid, but then I thought it would be a good time to get a second tumbler for my car, so I don't have to carry it to and from the house every single time I drive somewhere. This is by far the best 40oz tumbler I've ever tried. First, it fits in my car cupholder without any inserts or converters (not true of some other brands). Second, it is lighter weight than some of the competitors. Third, and most importantly, my water stays cold for a VERY long time in this tumbler; water gets warm much more quickly in the 40oz "Y" brand version I tried. I think the flip closure on this brand's lid is what does the trick so well: it snaps very snugly over the mouth hole, and in the process, it inserts a pin in the airhole, sealing the cup very well. That closure also makes it nearly leak proof, at least for casual use. This is also a much more versatile tumbler. The mouth hole is large enough to give me a good swig every time, or I use one of its metal straws in the car to make it safer for drinking and driving. The 40oz version of that other brand only offers a straw opening, which is very limiting to me. I tried their 30oz version, which has their standard lid, but that doesn't keep the water cold for very long, and it's much heavier. The lid for this tumbler fits snugly in place via a rubber seal ring. There's a lip on the lid to help you remove it (it does take a strong hand, since it fits so well). I used my first lid for at about 2 years, opening/closing it at least 2-3 times a day, and it had only just begun to get a bit looser. The finish on this tumbler is of very nice - very hard to scratch the surface, and it holds its color very well over time. It does not sweat even in our warm summers (high 90's). The metal ring at the top is well-attached and will not come off. The inside of the tumbler is easy to clean with warm water and soap. I use a separate handle, to make it easier to grab and hold, but it's certainly not difficult to pick up as is, if you hold it at the point where the cup starts to get wider. The tumbler comes with 2 metal straws and a straw cleaner - a really nice touch, so you are environmentally conscious (metal straw) with an easy way to keep it clean. We keep several of these brushes handy, so I'm not sure how well this particular one holds up (it got mixed in with the others, we can't distinguish it). But we know at least that it holds up, since the original one is still in rotation from 2 years ago. Finally, quality does NOT have to equate to high price. This tumbler is regularly about 2/3 the cost of the competition I've mentioned, with higher functionality and versatility.
