Review: SUPERB FLASK - BEST I'VE EVER HAD! - 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. :-)
