Thermos - Charcoal Direct Drink Flask (470ml) Reusable Insulated Stainless Steel Thermal Coffee Cup for Hot or Cold Drinks, Vacuum Sealed Water Flask with a Leak-Proof Lid, 10hr Hot/24hr Cold

This is probably the best thermos I’ve ever bought. It doesn’t leak when closed, and the locking mechanism works perfectly. It keeps drinks hot for over 5 hours, which is impressive. Its compact size makes it a great fit for smaller bags. If you're looking for a high-quality thermos, I would highly recommend this product!

This Thermos flask is absolutely brilliant. I use it every day, and it keeps my drinks hot for hours — even after a long walk, the temperature barely drops. The direct drink lid is really handy and doesn’t leak at all, so I can just throw it in my bag without worrying. It’s a great size at 470ml, easy to clean, and the charcoal colour looks really sleek. Ideal for college, work, or travelling. Definitely worth it!

I have had mine since November 2019 and it is easily the best travel/camp flask I have ever used. It is easy to drink from or pour contents into a cup, it is rugged, the seals are still perfectly good even after 6 years and everything is easy to clean. I like it so much I have bought a another as a spare. I have no negatives but at just under 500ml it might be a little small for some people.

I wanted one of these mostly because - apart from travel - I suffer from insomnia and often wake in the night desperate for a hot cuppa, but if I get up and make one it wakes up Grumpy...so I lie there umming and aahing and often end up not bothering. An ordinary flask would do the job but then you have the faff of taking off the lid and pouring it into a cup/mug before drinking. My sister has a Contigo Travel Mug which she thinks is the bee's knees. Her mug cost around £23 and is attractive with a metallic pink, slimline design (there are other colours). I borrowed it to test it out, and made tea (with a teensy bit of milk) to take to bed at 10.30pm. Sure enough, at around 2.15am I woke up parched and sat up to drink my tea. I was gutted to find it lukewarm after less than four hours, so decided against buying one, although it is ideal for my sis as she takes it to work meetings where it only has to stay drinkably hot for a couple of hours. So I was on the hunt for something more suitable for my purpose, reading dozens of Amazon reviews as usual. Yes, I do need to get a life. So eventually I ended up ordering this Thermos Ultimate (cheaper than my sister's mug too!) and am so glad I did. My first experiment was taking my lovely, mellow filter coffee on a six hour coach trip to an airport (yes, six miserable hours on a bus). I warmed the mug with boiling water for half a minute first then filled it with filter coffee and a small amount of cold milk. Around two hours into my journey I decided to have a drink, and SCALDED MY TONGUE AND UPPER PALATE! So be aware, this travel mug stays very, VERY hot. Nevertheless, once I got over the pain (ouch!!) I was pleased, but I ended up having to take the lid off and blow on my coffee in order to drink it! It was still lovely, hot and tasty after the six hour journey and well into the hideous airport wait. Then I got on my flight and bought a hot chocolate to drink immediately, and a mug of tea, which I poured into the mug. This also stayed REALLY hot throughout the whole 3.5 hour flight, and I left a swallow in the bottom to test how hot it was later. Amazingly, it was still piping hot some seven hours after filling it. AND it didn't taste 'flasky' as tea often does when in a flask for a long time. When I tried out my sister's Contigo mug, I also very much disliked drinking from a slit in the rough plastic top. It felt quite unpleasant, but my sister says she doesn't use that; she takes the whole top off instead and drinks from the metal rim. I wouldn't like that either, I don't think. However, this Thermos Ultimate has a funny little 'cup bit' that is quite pleasant to drink from, so I am very pleased with that too. It doesn't look as funky or trendy as the Contigo or other, inferior but pretty thermal mugs, but this Thermos Ultimate is so much more efficient and pleasant to use. It does not leak at all, either! Mine was upside-down in a carrier bag being bounced around for hours, and was fine. I've not tried it for cold drinks yet, but I assume it will be fabulous for keeping those freezing cold too. In fact, I would imagine ice would stay as ice for quite a while in this!! All in all, VERY chuffed with my purchase. £18 well spent.

I bought this as a deal, with a 900ml thermos flask. They are both brilliant flasks. Touch wood I have never had one leak yet. The teal and stainless steel one I purchased from thermos website. They are much cheaper at £18.40. No matter what colour you get, and free delivery no matter the cost. I use these for in my car, gym and hiking too. There also handy to have. They definitely keep things hot. I put a hot coffee in it put it in the fridge for 6hrs, when I took it out it was still steaming hot. If I am hiking I wrap it in a sock. I have tried contacting thermos directly to see if I can but a sleeve separately. But that was 3 weeks ago. Customer service is non existence. Be careful too as the label on the flask says dishwasher safe, but the instructions inside the flask say handwash only. I only ever handwash them. I have used thermos for the last 15 years with no problems at all. So fingers crossed. That these can live up to there older flasks.

Been using this flask the past year now essentially every morning for work, the coffee is still warm by lunch time which is grest as I like to just sip it throughout the morning. It's seal and lock is very good, doesn't leak and easy to clean by taking off the rubber bits from the seal. Only thing is the Thermos branding has washed off at this point but to me doesn't really matter but I know it will to some people.

Keeps drinks very hot for a long time. Would highly recommend for its long lasting thermal qualities. I wouldn't drink anything hot directly from it though, because you are likely to burn your mouth.

The thermos is great, amazing really but I'm sure the rest of the reviews easily tell you that. What they don't tell you about is longevity and the warranty, longevity in my case wasn't great it lasted a year and that was me taking good care never to drop it or put it in the dishwasher etc. The warranty however, absolutely brilliant, I called up Amazon to tell them my flask doesn't hold heat anymore and it states a five year guaranty, I honestly didn't expect much since most companies make it impossible to claim anything after a year, but no the guy was instantly like "thank you sir I've already ordered your replacement", three minute conversations and it was on its way prime delivered to my house. If this updated review helped, then please click helpful, no one ever does but it makes me want to leave reviews to help people out, cheers!
