Thermos Stainless King Travel Tumbler & Multi- Purpose Flask- 470ml Insulated Hot & Cold Water Bottle for Daily Commute & Weekend Adventures - Sleek Design in Raspberry, 5-Year Durability

I've been through my fair share of travel mugs over the years. Some leaked, some didn't keep drinks hot (or cold) for more than an hour, and some just felt flimsy. Then I met the Thermos Stainless King Travel Tumbler 470ml, and my world changed. This isn't just a travel mug; it's an investment, and honestly, it's the best in its range, hands down. From the moment I picked it up, I could tell this was a premium product. The stainless steel feels solid and substantial in my hand, and the sleek design is really appealing. I opted for the matte black, and it looks incredibly stylish. The black colour does indeed look classic. Positives: The absolute star of the show here is its thermal performance. I'm not exaggerating when I say this tumbler keeps my coffee piping hot for hours. I'm talking about pouring it at 7 AM and still having a wonderfully warm brew at lunchtime, even if it's been sitting in a cold car. For cold drinks, it's equally impressive. I've filled it with ice water in the morning, and the ice cubes are still largely intact by late afternoon. This is a game-changer for long commutes, days out, or even just keeping my drink at the perfect temperature while I'm working at my desk. The "DrinkLock" seal lid is brilliant. I've never experienced a single leak with this tumbler, no matter how much it gets jostled around in my bag. The design of the lid also makes it easy to sip from, and the integrated tea hook is a nice touch if you're a tea drinker like me. It feels robust and well-engineered. It fits perfectly in my car's cup holder, which has been an issue with some wider mugs in the past. It also feels comfortable to hold, with a good grip. Despite its robust build, it's not overly heavy when filled. Negatives: Let's address the elephant in the room: the price. Yes, the Thermos Stainless King is undeniably pricey compared to many other travel mugs on the market. When I first looked at it, I winced a little. However, having used it daily for months now, I can confidently say that you truly get what you pay for. It's an investment that pays off in daily convenience and satisfaction. The biggest "negative" for me, and it's a minor one, is the cleaning aspect. Due to the various components of the lid (the seal, the lever mechanism), it really needs to be disassembled and cleaned properly after every use. If you don't, you can get a build-up of coffee residue or milk, which isn't pleasant. It's not difficult to take apart and reassemble, but it does add an extra minute or two to the washing-up routine compared to a simple screw-top mug. It's a small trade-off for the excellent seal and thermal properties, but it's worth noting. Conclusion for Potential Buyers: If you're on the fence about the Thermos Stainless King Travel Tumbler 470ml because of its price, I urge you to consider it. While it is certainly a more expensive option, its performance in terms of temperature retention and leak-proof design is, in my opinion, unmatched in its category. It's a premium product that delivers on its promises. Just be prepared to give it a proper clean every single time you use it – it's a small price to pay for such a fantastic, reliable, and high-performing travel companion. If you value a hot drink that stays hot (or a cold one that stays cold) for hours on end, and you want a tumbler that won't let you down with leaks, then this is absolutely the one to go for. It's the best in the range, period.

Great thermos, I bought it for my long Saturday hikes and it’s been tried and tested, happy to report it does hold up! Tea was still nice and hot yesterday 5 hours after making it, very pleased I’m getting my moneys worth as I wouldn’t usually spend over £20 on a flask, but in this case quality is worth it. Very pretty red colour too hope it doesn’t fade

This travel mug does a good job of keepjng beverages hot. (I have never used it for cold liquids.) The key is to properly prime the thermos with boiling/ hot water and wait 10 minutes before emptying and immediately refilling with your beverage of choice. Also, leave very little head space when finally filling with hot liquid. These steps take a bit more time, but the results are worth the effort. By doing this, the flask performance will meet the stated time the literature claims the contents will remain hot. It is easy to use and clean. It feels substantial, durable, and is holding up to daily use. It does not leak, unless the lever (Open/Close) has accidentally been left open or cap has not been screwed on tightly.

I love this cup, I can make a hot drink and it’s still warm 9 hours later, not hot but warm enough to still drink. The main body of the cup is quite durable too, I’ve dropped mine a few times and though it dents it doesn’t make a difference to it’s functionality, although I have had to replace previous ones as the plastic lid has broken when dropped meaning it doesn’t seal. It’s easy to take apart and clean, can go in the dishwasher but i wouldn’t recommend it as it leaves a chemical taste for a while after.

I have had this item for a few months now and it is used every working day. It keeps my long black hot and pleasant to drink from making time at around 06:30 until I finish it at around noon. A good 5.5 hours is better than anything else I have ever used. It is strong, easy to clean and is leakproof once closed properly. At 6.46cm measured across the base, it fits well in the cup holder in my van and also in every loan car I have used. One star lost however because the paint is not particularly robust, which is a shame because the finish is very pretty, in a sparkly, shiny fashion. Mine is due to have the cup holder section repaired with stone chip paint, or something equally durable. Do I recommend it? Yes! Would I buy another one if this one went missing? In a heartbeat!

A truly fantastic travel mug. I've used this every day for the last 6 months and it's still in perfect working order. Definitely worth the extra money over the cheap and low quality flasks on here. Keeps drinks hot and cold for 12ish hours. 10/10.

Excellent flask. No leaks so far, doesn't seem to taint too readily though I only use it for coffee so hard to say for sure. Temperature maintained over many hours - keeps coffee hot to warm for an entire working day of 8 hours - and fits cup holder in car perfectly. The open/close function adds security against leaks. Ideal.

Fantastic. Keeps my coffee hot for hours. Dismantles so you can keep it clean.
