Beast Tumbler - 900 ml (30 oz), Aqua Blue | Reusable Stainless Steel, Vacuum Insulated Cup | with + 2 Straws & Cleaning Brush | Double Wall Travel Flask Perfect for Hot or Iced Coffee | BPA Free

I bought 2 of these, a 20 oz for my daughter to take to Uni and a 30 oz for myself (currently OOS). I don't often leave reviews, as a lot things these days are mediocre at best and crap at worst. Not these 'beasts'!!! They are amazing! The seal fits really well and is easy to put back on if you remove it for cleaning, as I do. It keeps cold drinks cold for over 24 hours and hot drinks...I had a hot chocolate in mine and forgot it had been made. 4 hours later it was still piping hot, to the point I left the lid open for it to cool down!! The eco friendly straws and cleaning brush are a bonus, you don't often get them included with flasks/mugs (my partner calls then cups, I say he's wrong and they're flasks, but hey, potato potaato 🤷‍♀️ I have bought numerous other brands, both from amazon and other places, in a long search for the perfect flask. And now I have found it. The old saying "buy it cheap, but it twice" is definitely true, as is "you get what you pay for". I actually don't mind paying more, for a product that genuinely does what it claims to do. And this product does. I have a kitchen cupboard full of plastic ones, metal ones, some leak, some are impossible to get clean, some can't go in the dishwasher, some are going rusty....I'm sure you get the picture. These Beast tumblers are worth every penny. I've spent less on others, which ultimately leak and I've spent more on one "dishwasher safe" one that is going rusty around the top now. If you are looking for a high quality flask, that can keep your drinks both piping hot and freezing cold (I'm intrigued about the icecream idea from another review 🤔) THEN THIS IS THE PRODUCT YOU NEED. What's more, there are so many different colours, with colour co-ordinated lids, the whole family can have their own with no confusion over whose is whose. Can't recommend these highly enough 👌

It is so rare to actually purchase something nowadays and genuinely get what you pay for! Or to put it in a better way, something of decent quality. As many cut corners or try to find ways to min-max profit, quality is rare (unless you pay exceptionally high prices for something), which not many of us can do and when you do get excellent quality for a reasonable price it's a lovely and rare feeling :) Pros: •Huge capacity 40oz (1136ml) Over a Litre •18/8 Food Grade Stainless Steel •Insulated Vacuum Layer •Hardwaring Slightly Textured Coating helps me grip. Great colours. •Decent quality Thick, Food and Heat Safe Plastic Lid, With clever leak proof seal and nice simple hinge. •Easy to clean, keeps an entire pot of coffee hot for at least 6 hours, keeps cold drinks cold (Ribena and Ice still had Ice in it all day). •Comes with Two Stainless Steel Straws and a Straw Cleaner. Nicely Packaged with a lifetime guarantee. •Simple, straightforward design, it works unlike other brands with smaller cups that I've tried which leak or break almost immediately. Cons: •Handle (Also cleverly designed and good quality moulding and material) sold separately but I can forgive this because of the exceptional quality and need to recoup material costs for production. To sum this up it inspired me to give it this glowing review which I rarely do, It's easy to maybe look at the price and think it seems a bit high but for less than thirty quid it really isn't, this simple design with quality materials IS NOT cheap to produce, they are making a profit but the price is fair and equivalent to a top end big brand, with I think better Quality and beats a cheap plasticy generic version with poorer materials hands down. Dont spend a fiver and dont spend fifty quid get this instead. Time will tell how well it lasts before the lid looses pressure or leaks or if it scratches, but I can tell for the quality it is, that even under my heavy use it should last for a fair and reasonable time, they do have a guarantee and I'll happily give Greens Steel more money for the next one even if its not under warranty. Buy One it's phenomenal! :)

Great size & quality. Love the colour. The lid doesn’t crack like my old one. It’s okay to hold but I’m definitely going to buy a larger one with a handle for ease and use this one for my coffee. The steel straw is narrower than my other ones which is good as I add lemon to my sparkling water drinks and worry about it eroding my teeth with wider steel straws. I’ve only knocked it over once but the lid stayed on and minimal water escaped through the sip hole. The paint hasn’t chipped like my old one. It keeps my cold drinks perfectly cold. My hot drinks hot. My only regret is not buying a bigger one with a handle. If you have smaller hands, I’d recommend a handle one.

A great cup, Hard to get the machine oil taste out the cup, I think this is why the lid might pop up first few goes. Hold heat very well. Rain collects on the lid rim as the lids recessed that’s a bit of a pain. Would like to see a more outdoors cold temperature and rain friendly lid option.

This tumbler is built for serious temperature control. Whether you're sipping hot coffee on a cold site or keeping water chilled through a long drive, it delivers. The double-wall vacuum insulation keeps drinks hot for up to 12 hours and cold for 24+ hours. Ice stays solid overnight1 . The powder-coated finish gives a solid grip—even with condensation—and the electro-polished interior prevents flavour transfer. No lingering taste from yesterday’s brew. The splash-resistant lid seals tight, and the included straws and brush make it easy to switch between drinks and keep things clean. ✅ Pros Excellent insulation—hot or cold for hours Solid build—doesn’t dent or warp easily Lifetime warranty—backed by Greens Steel1 Includes straws + brush—ready for any drink Dishwasher-safe—easy cleanup No flavour carryover—electro-polished interior Fits most cup holders—despite large capacity ⚠️ Cons Bulky when full—not ideal for small bags Lid isn’t fully leak-proof—splash-resistant only No handle included—sold separately (Beast Handle V1) Premium price—but justified by durability Not suitable for carbonated drinks—pressure build-up risk 🧍‍♂️ Personal Verdict Used this on site and in the van—coffee stayed piping hot past midday, and iced water held up through a full shift. The grip’s solid, the lid seals well, and the straws are a proper touch. For under £25, it’s a beast of a flask that earns its name.

I kept seeing people going on about these new cups all over the internet and tbh I wasn’t buying into the hype. They look like a thermos flask to me, with a straw so I wasn’t exactly understanding the price or the demand. But curiosity got the better of me and I had a look on here for them to see what magic powers they offered that I was clearly missing from my life. Well, an hour later, I had come to my conclusion and had found a Beast cup/mug on here on a lightening deal. Being as I drink around a litre of coffee a day, I figured I’d buy the biggest one, save me keep having to go make a drink 3 times a day. And so far, I’m impressed. The quality is brilliant, it’s easy to clean, looks sturdy and is not overly heavy. It fits in my drink holder in the car and I can make a coffee at 9am and it’s still hot at 4pm. The lid seems solidly made and spill proof. I’ve not as yet had any accidents but I’m not making any claims to how well it would last if laid down or tipped over with fluid inside. What I can say is when I’m walking around with it, if it’s sealed then I’ve not had any issues with things getting wet. The straw gets a bit hot with hot drinks but I invested in the little rubber tips and that solved that issue. I’m going to look at investing in a handle for it since it’s now a daily staple in my routine. The other half was also so impressed with my find he insisted on getting one too. For anyone who wants a large, thermos mug without the price tag, check out these cups as they are certainly good quality and worth the money.

This Beast tumbler is amazing. Keeps my water ice cold. 900ml is a perfect size as well, not too big and not too small. Tested it for leaks by turning it upside down and shaking it. 100% leak proof. I haven't used it for a hot drink yet? Not sure I will as I mainly use it for my filtered water. Haven't used the the straws or straw cleaner either yet. Nice little extra to have nonetheless. Get one you won't be disappointed!

I have been using this for hot drinks for a long time now, I love it. In fact this is my second one, because the first - which was a gift - heartbreakingly fell out of a side pocket in my bag at a train station and could not be retrieved. I *had* to have another. It keeps drinks hot so long I can make one in the morning and it'll still be drinkable temperature - *enjoyable* drink temperature not "lukewarm and chug it" - multiple hours later. I could make a super hot drink last thing at night and drink it in the morning. Today I bought a nice ice drink around midday, and finished the drink by about 4pm because I was slow. There was still a ton of ice in the drink. It is now **MIDNIGHT** so it has been 12 entire hours and there is still fully frozen ice in this thing! If I had put that ice in a cup in the fridge it would've melted hours ago. I'm not joking, I had to go back to find this purchase and make this review because I'm sat here astonished. I'm tempted to leave this half cup of ice all night and see if it's still frozen in the morning. I want to get another one so I can take ice cream out on a hot day with a spoon and see how long it's still edible and not a weird runny soup. I think this mug has genuinely broken the laws of physics, it's a portal to some other dimension where temperature remains near constant. I've had electrical appliances with less insulation than this thing. What do I do if the ice is still ice in the morning? Is this the permafrost? Update - it has been over 24 hours since I put ice in the mug, it's still there. There's about half the volume as before but this thing will not let it melt! The first photo was after 12 hours, the second after 24 hours. There is some tea staining on the inside of the mug but I'm not bothered by that, I use it literally all the time, constantly, and it gets a good clean between uses, it's just common for tea to stain metal.

I like so much 🥰🥰🥰🥰 the color is so beautiful🥀🥀🥀🌹🌹🌹

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.

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.

Absolutely great

J'adooore ! J'ai eu beaucoup de mal choisir MON petit thermos : la capacité, l'aspect, la facilité d'entretien, la qualité, le prix... bref, j'ai beaucoup comparé ! Et puis je me suis laissé tenté par celui-ci en couloir noir : sobre, classe, passe-partout... Ma crainte principale était sur la facilité ou non de nettoyage. Car de cela allait dépendre mon envie de l'utiliser régulièrement OU PAS ! Mon objectif premier dans l'achat d'un tel objet était de boire davantage car je ne bois pas assez dans une journée. J'adore le thé, les tisanes, etc. et lorsque je me prépare une tasse je l'éloigne généralement de mes documents de travail pour éviter une catastrophe... bilan : deux fois sur trois JE L'OUBLI et ma boisson est ensuite trop froide ! BEURK ! Bref, désolée je m'égare ! Donc il fallait que je trouve une solution pour pouvoir mettre la boisson près de moi, sans qu'elle risque de se renverser ou sans risque que ma chienne vienne mettre son nez dedans, et sans qu'elle se refroidisse si je suis concentrée sur mon boulot pendant une heure. Et bien BINGO !!! J'ai trouvé ! J'adore d'une part parce qu'effectivement ma boisson reste bien au chaud ! Le thermos est bien hermétique : au début il faut laisser un peu la vapeur sortir avant de fermer complètement sinon ça fait effet ventouse et la pression lui fait perdre un peu de sa capacité d'étanchéité, mais une fois qu'on a compris ça, c'est IMPEC ! D'autre part, et c'était un point essentiel pour moi : IL EST FACILE D'ENTRETIEN !!! Du coup, quand j'ai laissé mon thermos sur le bureau pendant plusieurs heures je ne recule pas à l'idée de le laver rapidos plutôt que de le mettre au lave-vaisselle (même s'il y a déjà fais un tour ou deux) pour pouvoir le réutiliser rapidement. Concernant le maintien au chaud, je n'ai pas été très attentive au nombre d'heures de maintien au chaud, mais il faut dire que je l'ouvre de nombreuses fois pour boire dedans et j'ai bien conscience qu'à chaque ouverture un peu de chaleur s'échappe. Néanmoins, je retrouve toujours ma boisson à une température agréable assez longtemps pour tout boire et ne pas gâcher ! Bref, je suis contente de mon achat et je recommande !!! A la votre ! ;-)
