Thermos Light and Compact Flask, Stainless Steel, Midnight Blue, 350 ml

I bought this flask as a replacement for my previous Thermos flask, which had come to the end of its useful life. I chose this one because I liked my previous Thermos flask, particularly for its excellent heat retention properties, and thought that this would make an ideal replacement and I also liked (and expected to use) the 15 year guarantee. I am a truck driver and use my flask every working day - nearly 270 days each year. My flasks (I have gone through numerous over the years, of various brands, and had found the Thermos make to be the most robust and the best insulator) get a pretty, actually, very, hard time. I am usually pleased if one lasts much more than a year. I normally pay around £10 for a flask and, although this one was a bit more, I have kept my receipt and guarantee, expecting, as I said before, to make one, or probably several more, claims over the 15 years covered by the guarantee. I could not have been more wrong! This new flask appears to be much stronger than all earlier models of any brand. Having used it now for more than 1 month, it is still totally unmarked - not a scratch or dent in sight! This is a first, as my flasks get pretty rough handling, bouncing about in my kit bag or when stored in my cab as I travel around the Country. However, I think the biggest improvement is in the combined stopper/pourer. This has almost always been the component to fail first, with the spring, clip or other moving parts breaking or failing - probably contributed to by limescale build up from the very hard water in my local supply. The pouring mechanism has now been completely redesigned and, so far, shows no evidence of being affected by limescale and, as the need for a spring has been eliminated, I do not now expect this part to fail. The effectiveness of the seal has actually improved too:- As I 'superheat' my coffee in the microwave before pouring into the flask, condensation has always gathered on the inside of the lid/cup on all previous flasks - especially after the first cup had been poured. This has led to dripping and/or leakage each time the lid was removed. This new flask, though, suffers from negligible condensation and has not yet dripped once. The final benefit of the newly designed stopper/pourer is that my coffee is kept hotter for longer. My previous Thermos flasks would keep my 'superheated' coffee hot for 12 hours, or a little longer, if the stopper had not been opened earlier. This period was reduced proportionally according to how many and how soon I had poured drinks before the 12 hour mark. Possibly due to the improved seal, I find that I can now have an earlier cuppa or even cuppas and my coffee will still be hot for up to about 12 hours. If the flask is left unopened, the contents are still piping hot up to around 14 to 15 hours after filling. I cannot comment on the effectiveness of keeping drinks cold - I use mine only for hot coffee. As you can probably tell, I am delighted with my new flask and I would heartily recommend it to anyone who might anticipate similar using and 'abusing' of their insulated drinks container. :-)

Keeps liquid hot for a very long time

Bought for travel (having used it previously) and fits nicely in a baby bag. Good quality slimline flak, easy to carry around and the pushbutton feature to release the water is really handy. Keeps water hot (although not for the full 24 hrs), but overall happy with the purchase, highly recommend

This is the only flask to have as a lorry driver, keeps temperature and does not leak, smart looking and robust, and spout? separates for cleaning. Only really annoying this is the stickers will take hours to get off.

I have tried various flasks for hot water to make baby formula milk. Of the ones I own, this is the only one that retains heat for a long number of hours.

Thermos is a great brand and this is another great product from them. Ideal size for me to take on hikes (fits in my rucksack side pockets) or when playing golf in the winter months. I have used it on many occassions and it has stood up to knocks and bangs, resisting damage. Multi functional as it keeps the hot drinks hot and cold drinks cold. It has never leaked. The lid is a neat sized cup.

Keeps drinks hot and durable. Decent size and lasts throughout the day.

The Thermos flask keeps drink hot for several hours.
