Stainless Steel Super Light Travel Tumbler, Matt Black, 470 ml

Compared to my previous glass based Thermos flask(Thermos Premier Double Wall Flask 500ml) this product has many advantages. Advantages: Amazing how thin the gap is between the interior and exterior of the flask is. Although having a similar capacity it is about 2/3rds of the exterior volume and takes up much less room in my bag. I like the design that you can direct drink from the flask. I like that it is a metal flask so unlikely to break. Wider neck and easier to clean than the previous glass flask. Fits into cup holder in car door. I measured the temperature of the drink after 4 hours and recorded 79.5 degrees centigrade with my thermometer held in the centre of the flask.(78.5 in my glass flask) This is after filling the non pre-heated flask with boiling water and immediately before sealing the flask measuring 94.5 degrees centigrade and keeping the flask in a room of at 18 degrees centigrade. (note I found that it made less than one degree difference after 4 hours if I pre-heated the flask first) In any container, the taste of tea changes the longer you leave it after brewing as the good compounds break-down over time.(especially if the brewed tea is kept hot) I find that after a few hours after brewing the best of the tea has gone. This tumbler/flask has the ability to keep the tea more than hot enough to drink, far in excess of the time which hot brewed tea can usefully be kept, but I accept this as, the convenience of having my own tea far outweighs the disadvantages. Conclusion: Really happy with this Tumbler/flask as I usually consume my hot drink within a few hours when I use this flask.

I bought this a couple of years ago and still use it every shift I work, great value for money, hasn't leaked on me in three years, it's been dropped, left outside, kicked the whole lot and hardly has a scratch on it. Really excellent quality. This takes between a medium and large Starbucks coffee in it and keeps drinks hot for up to 8 hours in my experience (I work outdoors) and is ideal for my usage case.

Delighted with this flask/travel mug. I wanted one to keep drinks hot for upcoming knee surgery so that I could have a hot cuppa in the morning and it does stay hot. Plus I can ask my family to bring it in on visits to hospital as you cannot get a decent cuppa there. Easy to clean and looks good too. I am about to throw out all my old flasks as this is so much better!! Also it fits the car drink holder so I will make good use for long journeys and when out in the garden. Was worried at the price but pleased, it's worth it as it does what it says on the label

It arrived when they said it would . I love a nice hot cup of tea by the time I have finished it is cold , today I made a cup of tea in this thermos and Yes! I had a hot drink right up until i finished 💯

I love this - light weight, fits well in my rucksack, totally leakproof. Keeps coffee hot for hours. Only downside is size - too big! Please make it more like 350ml.

This mug is so light-weight in comparison with my others that I sometimes think I’ve forgotten to fill it! Great heat retention, better than other big brands, really easy to clean too so love this travel mug but had a very different experience with the rose gold version.

Amazingly light and keeps drinks hot for a ling time. Only downside is I keep burning my mouth as I don’t expect it to retain heat as well as it does.

Great item, does what is meant to...

My second one ordered, Amazing product quality!! Almost most expensive bottles u can find but one that really lasts and not a drop of spill when tightened. This is second one ordered, product is great but this time no retail package but given the premium price I expected to see a retail box inside the Amazon box at least (not just the bottle in a plastic bag)
