Thermos Discovery Tumbler, The Flask I was Looking For

It looks nice, and more importantly it does not leak, even if you put it upside down. I carry it to the office every day, and enjoy hot tea all day long. I have now bought two of these, one for myself and one for my wife.

This cup is very nearly perfect for my needs. Only one problem – i have a 2 hour commute, for which i like to have a cuppa. But it keeps the drink too hot to drink even by the end of my journry. Not insurmountable with a little planning, and a great cup apart from that.

Every one that sees this coffee mug wants one, so this mug is excellent in every part easy to clean easy to operate buy this one if you want coffee up until one o’clock which was made at 6. One grip you have to look out for the hole before you drink out of it could have an indent so you could feel with your lip thanks.

Comments from buyers

“Wish I’d bought one years ago, A very effective thermos if a little difficult to drink from, Finally, a mug that keeps hot drinks hot, even with the lid off.”

Comfortable to open and close for drinking. You can disassemble the lid for cleaning. Great tumbler, but the lid is fragile, it broke after drop on the floor. One annoying thing – you always must visually inspect it before drinking, because there is no tactile feedback is it open or closed and you must locate where the drinking holes are – not good when you driving.

Bought this for my husband and he tells me its the best flask he’s had, keeps his drinks hot for ages. . Dont put it in your bag like he did as it will leak.

Excellent beakers, they really keep the drinks hot for ages. Good for drinking in the car.

– 100% leak proof- has a small red tape around the open/close button that signifies if it is open or not(pressed in), so you know before you ‘tumble’ it. – keeps hot coffee hot for many hours. – stain-free hydrophobic steel alloy, means you don’t even have to use soap and sponges to clean it, just wash it with water (although washing it is advised, of course). The lid/cap is also made out of hydrophobic elastic(soft) plastic which means your drink won’t stick on it and stain your bag or whatever it is you carry it in. A bit on the expensive side, but you definitely get what you pay. If you need a reliable mug to carry around fearlessly, this is it.

This is effectively only a flask, for keeping drinks hot etc, however it looks absolutely beautiful. I’m only replacing my existing thermos tumbler of 2 years, as i dropped it once too often.

This is the best thermos iwe ever had. I do recomend this strongly, and will get a new one in the future if needed.

Read a bunch of reviews for this product before buying, and there seems to be some variation in people’s experiences. Here are my 2 cents:1) it really keeps stuff hot. If you make a cup of tea and put the lid straight on, it will be way too hot to drink even a few hours later. I’ve had to add a bit of cold water before putting the lid on, it stays amazingly hot for a long time. 2) a few reviews says the product is leak proof. Hold it upside down and a few drips seem to come out. Over a day it could get messy. So i would not risk storing it inside a bag. It would be fine in an upright external pocket though e.

I have to make my tea and leave the lid off for 20-25 minutes otherwise after 3-4 hours it is still too hot to drink. Not a complaint, a compliment on the performance :-).

Very good, highly recommended. Completely leak proof, sat on its side in my bag with a full cup of coffee and none spilled. For a travel mug it’s very easy to clean. The only slight down points are (according to the girlfriend) its a bit on the heavy side and quite hard to unscrew, which in fairness might be more my fault as i like to make sure its done up. Oh, and it does keep liquids hot for the amount of time stated, especially if you pre-warm it with some boiling water before you make your drink in it.

Fabulous, after lots of help from owners of the tumbler, information that should be supplied by the company, i now can use it with confidence. The information provided was written by a very thin spider, perhaps specs could be provided, in future parcels.

This is my fifth mug in searching for a mug that does not leak and holds the beverage hot for acceptable time. The previous mug contigo autoseal travel mug (silver) was good but it got rusty after just 2 months. I decided on this mug and it delivers on both requirements. It is 100% leak-proof and it holds beverage hot for more than the advertised 5 hours. I’ve also tried some cold beverage and it stays cold for around the advertised 9 hours. Cleaning the mug is easy, though one has to dismantle the led to clean it and make sure the smell goes. It can easily have 5 stars, however:1. The led has two wide drinking slots that are opposite to each other. I have no idea why is that as it one is not used all the time.

Some reviews say its lid tastes of detergent after a while and the press button leak proof lid leaks after a while. If you think about it, this tells me they have not cleaned it properly or rinsed it under a running tap afterwards. Not realy, better than a leaking lid when laying on its side. I made a coffee (black, no milk) in this at 11pm and its was still hot enough to drink at 7-8am the following morning. Stick that up tour jumper mr difficult too clean tastes of soap.

This is all i was looking for in a thermos tumbler. It is well built with thick steel sheeting, high quality plastics in the lid and a well functioning click-to-open/close mechanism in the lid. Screwing and unscrewing the lid is like using a large metric bolt, it just catches the thread and steers without jamming at all. You may think the design lends itself to the tumbler easily falling over but since it is so solidly built and therefore has some weight, it isn’t so. It also fits in the cup holder in our cars. Have you ever felt that coffee or tea tastes different in different cups?. The lip of the lid is also well designed and for me has a nice feel to it.

Very well insulated thermos, simple to use and to clean as well. It’s large enough to hold a significant amount of drink. The lip helps with drinking hot liquids as well. Satisfied with it’s function, a useful thing to have especially in cold climates.

I was looking for the wide open design that easy to clean. This is just righti also use this tumbler at coffee shop for takeaway coffee. Put it in my bag doesn’t leak and keeps my drink hot while travelling.

Only received it today so i can’t really say how long it keeps things warm but it kept my tea warm for about 3 hours while i was sat at my desk but i finished it before it cooled down. At first i thought the seal was broken after taking it apart to wash as someone else had mentioned that it was only good for the first use in their review. It turns out that the little part at the bottom of the mechanisim that goes around the hook actually has to be turned clockwise to lock into place, now the seal is perfect and doesn’t leak at all, i stood at my sink and flailed the flask around and nothing came out. Another thing i’d like to note is people saying that the button stops clicking, from what i can tell i think this is pressure in the flask, unscrewing the lid slightly and then pressing the button aleviates the issue. I mainly had this when i overfilled the flask a bit. Edit 4/5/17:still have it and it still works fine, it’s been bumped around a little bit with a few scuffs on the casing but everything is still as good as it was when i got it.

I make myself hot lemon water before i go to bed to put on my nightstand ready to drink in the morning and it’s still too hot to drink. Equally good to take on holiday and transfer your cold drink into so it doesn’t get warm sitting in the sun. No one enjoys hot beer on the beach.

I have used the mug when traveling and also at the office and it does work as advertised, in that it keeps the tea hot. Also, i’ve had no leakage while carrying it around in my bag. So far, i’ve used it only with hot tea and haven’t tested the ‘keep cool’ part. The cap open/close button is easy to operate but each time i drink i do have to look for the slit where the beverage comes out of and make sure i’m not holding it sideways. No issue for me, but it might be an issue for some who want to use it while driving without taking their eyes from the road. In/on the cap there is a ‘teabag hook’ which shows consideration from the producer but i’m not sure how necessary it is. Both the main body and the cap are easy to clean however i’ve only used it with tea, so if using it with more nasty , creamy stuff, it might not be so easy to clean out the cap. It is reasonably well made for the price – have no complaints. Mine came in bulk packaging (i.

I’ve spent a lot of money over the years tring to find a decent travel cup that doesn’t leak and keeps your drink hot but also the container has to look nice. I decided to try a thermos as their flasks have always been brilliant. I chose this particular travel cup because of the way it looked. The picture shows the product information on it with the red and blue printing and i thought it looked fab. Was very disappointed to find when it arrived that it is just completely silver. I can’t knock the quality though and it’s capability. The container keeps my coffee as hot as when i first made it hours after. After 2 hours the coffee is still too hot to drink. However you do need to pretreat the flask by filling with hot water for 10 minutes to get it to stay hot. I would recommend but very disappointed with the look of it.

I’ve deliberately taken a while to review this cup because i wanted to see how well it performed before giving an opinion. I love it and can’t fault it. I fill it with coffee around 6am – cycle to work with it in a pocket on the outside of my rucksack and even in low temperatures when there’s frost on the ground, the coffee is still scalding hot at lunchtime ( early afternoon). It’s been dropped, fallen off the back of the bike and bounced more than once across a car park, so it’s now looking less than perfect, but it’s still doing what i bought it for – keeping my coffee piping hotwell worth the money.

At last, a mug that keeps my coffee hot and is leak-proof. This mug does what it says on the tin, it keeps liquids hot for over five hours. It’s easy to hold, stylish and fits well into my car’s cup holder. On a ‘test’ run i filled it up with boiling water at 10 in the evening, the water was still reasonably hot at 7 in the morning. A wee bit of a fiddle to clean but i feel it’s well worth this small extra effort for a mug that keeps my tea/coffee hot when i am on a long journey.

    I’ve only used it for tea and coffee as yet, but this is awesome. It keeps hot drinks hot for far longer than anyone needs, even with the lid off. Thermos have created exactly what i always wanted, a mug that keeps hot drinks hot till the last drop. I would highly recommend this to anyone that prefers to drink their hot drinks hot. I’m looking forward to seeing how it goes with drinks with ice in in the summer.

    Only hesitation is the white lid which is hard to see if it’s open or shut. And being bright white im anticipating it’ll discolour.

    Good quality however the rubber sealing tends to hold on to the smell. And taste of anything inside the cup and is quite difficult to clean afterwards and get rid of the taste/smell.

      I bought this as a replacement to my previous thermos discovery tumbler 470 ml which was still under warranty. I would hae given this 5 starts all day long if it were not for some kind of slight awkwardness with this one when drinking. The liquid occasionally comes out at a funny angle and can end up dribbling down your chin, an issue i never encountered with the previous one.

    Keeps my coffee hot for at least eight hours and i mean hot. Best to prewarm with boiling water for a few mins while i heat milk for latte in microwave. I do dismantle lid every few days and soak to avoid smelly milk skin gathering in the lid.

      I have filled it with hot tea/milk/coffe and lying it on the table/soffa/backpack several hours. Not a single drop has left the mug. – aesthetics: elegant finishes. I bought the gray because all the painted-thermoses that i got before, lose part of their paint soon or later. – ergonomics: the shape makes that it doesn’t slide down, is very comfortable even for my small hands. – time: i don’t drink boiling tea/coffe because i don’t like the sound of drinking liquid and air at the same time. But to test the product, i use boiling water and 4 hours later it was still too hot for me. Personally i’ll need to put a little cold water if i want to drink it soon. So yes, it keeps the temperature very well.

      I’ve had this mug for over 3yrs now and it’s still waxing strong. Bought it around 2012 ending or 2013 beginning. It keeps tea hot for even over 5hrs cos it keeps it hot for 5hrs then it starts going warm. I so much wish they could do like smaller or portable versions like 360mls or something like that cos this one is 470mls which is also good. I can’t fault this item anywhere. Body doesn’t get hot when you hold it. I carry it to work most times and it turns upside down my bag, i’ve never had a spillage or anything like that since i bought it. I will recommend this item 1000% anytime any day. Press that little button in the middle to seal or unseal. Little tip: when that button is flatter, means you can sip, when it is higher up, means it is now sealed.

    I’ve been using this daily for a few months now so it’s already outlasted most of my previous travel mugs. It looks good and keeps for the coffee warm. For hours and hours :)i only have one issue with the mug and that is keeping the inside of the lid clean. I soon learned to take the little nut off the lid and remove the plate and also the large gasket around the outside but it’s the little gasket on the opening and closing mechanism that cannot be cleaned as it cannot be removed (easily). I can see dirt (coffee?) under the translucent gasket and no amount of soaking removes it. I have read that you can remove the gasket with tweezers but, knowing me, i would damage it whilst doing that which would compromise the heat and leak proofing. So, 5 stars for usefulness but -1 star for the inability to clean it properly.
