Beast Tumbler - 1500 ml (50 oz), Arctic White | Reusable Stainless Steel, Vacuum Insulated Cup | with + 2 Straws & Cleaning Brush | Double Wall Travel Flask Perfect for Hot or Iced Coffee

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.

Good grip, sturdy , keeps drinks cold Haven’t used for hot drinks but would think it’d be equally good

"Enjoying" a "dry" February, I have found myself drinking a lot more water than usual. Regular trips to the kitchen to refill my existing 450ml vacuum tumbler was becoming a bit of a bore, so I decided to get something rather larger and which required filling less often. I was looking at buying a Yeti 30oz tumbler, but didn't much like the magnetic gimmick that was in place of a proper stopper; also, wanting a 100% Stainless Steel finish, rather than paint, the Yeti had an annoyingly heavily embossed logo on the main body, which looked like it could interfere with cupholders, etc., or at the very least, feel unpleasant when holding the tumbler. And then I came across BEAST. And forget a mere 30oz, how about a full 2 UK Pints (and some), with the 40oz model? Remember, this is to US "Fl Oz", and while their pints are just 16 of these units, the units themselves are bigger than the UK version. So 40 (US) oz equates to 41.6337 (UK) oz (thanks, Google!). Half filled with ice balls from the freezer, and topped up with cold tap water, the 40oz Beast keeps your sipping drink at 0c (give or take) for many hours on end. First time I used it, I left it overnight, and there was still some ice inside in the morning. The plastic top is well-fitting, and 100% leakproof (so long as it stays in place). A tethered flip-stopper gives you a pleasant drinking interface, and if you want to be extra lazy, two very nice Stainless Steel reusable straws (and a cleaning brush) were included in the package. The actual tumbler is flawless, perfect, smooth matte finish 18-8 Stainless Steel, and accidents aside, looks good to last a lifetime. And for what it's worth, the manufacturers are confident enough to have given it a lifetime guarantee! So all in all, this is one Beast of a tumbler, for its sheer size, and build quality. I love it already, and if anything were to happen to it, I'd by another without a second thought. Totally FIVE STARS.

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.

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 ! ;-)

This is a really great mug, that keeps my coffee warm for a long time. Highly recommend to anyone looking for a good firm sturdy coffee mug.
