Happy, happy, happy!
Excellent cup! Keeps drinks cold as well as any more expensive make. Came with two stainless steel straws and a brush to clean them. The straws tend to rattle a little when in the truck, so I opted to just use the seal tite closure on the lid while driving. The lid does screw in and it is leak proof when the closure is in place. The portion of the cup that sits in the cup holder is slightly larger in diameter than a yeti, so it may fit a little snug and not bottom out in the holder. Comfortable handle. All around, an excellent cup, certainly as good as any other and a little cheaper. Well packaged and fast delivery. Won't hesitate to buy another when needed.

Highly Recommend these!
Honestly couldn't be happier!! I bought six of these (different sizes and colors) 5 years ago and they still look and work like they're brand new. No leaks, no rust, no chipping of the paint. And honestly, I like the lids on these a LOT better than my husband's Yeti cups of the same size. They keep things cold for a very long time and I just love them. HIGHLY recommend!!

Finally, a perfect replacement and upgrade for my favorite mug.
I have been using the same 20-oz Aladdin mug I received as a Freshmen Orientation gift in college for the past 23 years. I have been somewhat nervous about my practice of drinking out of a mid-90's, frequently dishwashed plastic mug (most certainly NOT BPA free), but I never found a replacement mug I liked. I had tried using other metal mugs (the kind you get as freebies at conferences or sports events), but was frustrated by the sliders which trapped liquids and couldn't be cleaned (I drink homemade lattes daily, and trapped milk goes rancid before I even leave work for the day), and the mugs couldn't hold up in the dishwasher - a leak would always develop, usually in the base, and you could hear water sloshing around inside the "vacuum-sealed" mug. Additionally, these mugs were always 16 oz or smaller. I know that 4 oz doesn't seem like a lot, but I would always notice a difference when I ran out of coffee before I expected to. I decided it was time to find a replacement for my favorite mug. I wanted something dishwasher safe (that wouldn't develop a leak in the mug if washed and had a lid that was able to be easily fully disassembled and reassembled for thorough cleaning). It needed to be BPA-free, non-reactive (I use Essential Oils in my water, and would like to use them in my mug, which I couldn't do before, as they can react with plastic and aluminum, but are safe with stainless steel and glass), spill resistant (my Aladdin mug had open holes with no slider), insulated for hot and cold, fits in a standard automotive cup holder (my old mug was too big, but fit nicely into the center console of my mid-90's Outback (it's like they were MADE for each other!)) and had to hold 20 oz. The BEAST has fit the bill to a T. I have only had this mug for two days, and have only used the mug with the seal-able lid. My coffee stays hot until I have finished drinking it (which can be a few hours while I work at my desk). When my coffee is done, I can easily take everything apart and thoroughly rinse the mug and lid and refill with ice water with no lingering coffee flavor. I anticipate it will take a little to get used to drinking through a stainless steel straw, but I am VERY happy that this was included. A stainless steel straw will allow me to use this mug with essential oils, as I will be able to keep the oils away from the plastic lid by sipping through the non-reactive straw. An unexpected feature was the nose guard on the slider of the lid. I have had the experience with past mugs with sliders that, when I go to sip my beverage, the little tiny hole which is provided to allow air to enter the mug to replace the liquid coming out gets covered up and sealed by the tip of my nose as I drink, slowing or stopping the flow of the beverage through the drinking hole. This mug has a raised section which protects the air hole without preventing air from entering it. It is a little thing, but something I notice (with relief) every time I take a sip. The exterior of the mug is more compact than I expected, which is great. However, for some reason, it feels larger than it looks when I hold it. I have somewhat small hands (I wear Men's S or XS gloves/ Women's S or M depending on the style), and am finding myself holding the mug closer to the base for a better grip. I read the reviews from other customers and one of the tipping points for my decision to buy the BEAST was the customer service reputation from Greens Steel. I have received two emails from Greens Steel so far, checking in on my purchase to make sure I am satisfied and to let me know that they are available to help if I have any questions or encounter any issues with my mug. The reviews from the other customers make me feel like this concern and customer engagement is genuine and heartfelt, and as a result, I won't hesitate to get in touch with Greens Steel with any question I have, if necessary.

Beast vs. Stanley
I can’t say enough about this cup. I bought it January 2023 and it’s 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 haven’t 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 it’s 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.

Great cup, lid could use redoing.
Im a delivery driver in AZ so keeping ice for most of the day is very important to me. This is an awesome cup the handle cant loosen like most others, the ice stays ice for a long time,and its huge but can still fit in the cup holder. Now the negative, metal straws arnt feasible in AZ because of heat so I had to swap it out for a plastic straw. And unlike other cups this doesnt have a seal around where the straw goes so it will leak if tipped over. Also since it isnt really made for a straw you have to adjust the lid to which side you drink from. A new lid with a sealed straw hole in the middle would be helpful. Overall 4/5 stars

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.

Love it!
Love this tumbler. It is a press on lid which is perfect. I don't like the lids that screw on and vaccuum seal because they are a pain to get off and it is tricky to get the straw where I like it. This is the most beautiful tumbler that keeps things cold 15+ hours. It would make a great gift since it comes wrapped in a white cloth bag within a beautiful box. It comes with 2 stainless steal straws and brush to clean with as well. Dishwasher Safe. No handle to bother with in the car cupholders. Great value as well. I bought the rainbow one and the blue one. Pleased with both.

Great Tumblr for the price
I got the Tumblr and I love the color and it’s amazing. However, I am slightly disappointed at the fact that for paying this amount of money, I find a small crack on the plastic lid. It’s not the end of the world or anything, but it is kind of a shame that there’s a crack on the lid when I took it out of the box. However, I did just test it and it is leak proof.. the handle is very comfortable and the cup is easy to use is self-explanatory. The only downside is the screw on lid handle might be a little bit too small and it might be difficult for some people to unscrew it so just don’t over tighten it. It fits great in my cupholder. I love it.

Nie zakręcany
Niestety wieczko nie jest zakręcane, tylko na wcisk. Moze to być problemem jak kubek ma być używany w podróży lub między domem, samochodem, pracą. Małą nieostrożność i zawartość wylana.

Love this thing. Ordered another. Great company!
Absolutely love this tumbler. I drink a lot of coffee but unless it's cold I drink it slow. This cup will keep your coffee hot for hours. I've forgotten I had a cup of coffee still going in this thing, and 5 hours later I was dumping it out and there was still steam Coming from the coffee. Unbelievable product. The wife was so impressed she said I needed to order her one then and there so another is on the way. It's a large cup, fits in my trucks cupholders fine which is a huge plus. Just be careful when putting the lid on right after filling it. The steam and off gassing of coffee creates enough pressure that it will pop the lid right off as well as sending lava hot coffee all over your hands. Learned that once, never again! Now I just open the lid when putting it on and leave it open for the first 5-10 minutes. Not subtracting any rating for that as it's user error. This tumbler is perfect, I am not.

Colour ideal for me appears to be durable and it washes well and comes up looking clean Lid fits well and at present no leaks reported. Only used for cold drinks so far and it keeps it cool for a long time. For the cost good value for money there are some more expensive ones on the market. Pleased so far.
