Review: Thermos Ultimate beyond compare and a shrewd long term investment an - The Thermos Ultiimate drinks flask unique feature is in its ability to keep drinks scalding hot for 18 hours and hot for 24 hours. I purchased 2 of the smaller size (previous model) one for me and one for my wife about 15 or more years ago and they have never failed to impress on how hot they kept our tea or coffee. They are quite tough and resilient . Unfortunately I dropped mine once too many times , but without blinking instinctively reordered a new one within a heartbeat. Ooops, my eagerness caused me to order the larger 900ml size in error. I will keep it for hot water when we do go out together, as I drink coffee and she drinks Tea. I have already ordered the smaller size ( currently available from TK Max at under £20 and ordered on line for collection tomorrow I can’t wait). Originally I used it for work knowing wherever I was driving to around the country I had a hot coffee to enjoy and even if half drunk a very warm coffee at the end of the day before I started to drive home. I found the smaller size quite adequate to last me throughout the day providing 2 cups of coffee throughout the day. Life without one is almost inconceivable, that is how impressive the Thermos Ultimate flask is. I will keep the larger 900ml size and not return it as even though it is too large for my regular use as I’m sure it will come in useful on the odd but critical situation e.g. Overnight keeping water hot for the morning on a Trip or if I’m in bed unwell a hot drink to hand all day or overnight. It will also be great for cold drinks if going on a picnic or to the seaside with family . It may seem expensive but it truly is a long term investment. 20 out of 10.
Review: Fantastic Thermos Flask - Excellent! Couldn’t be happier with this Thermos Ultimate flask - looked online for top recommendations and this was always in the top 5. It’s had everything from coffee, soup and chilli in it. It’s easy to clean, use and pack into a rucksack. So far we’ve had no accidents, leaks or breakages. It’s easy to use and does a fantastic job of keeping food and drinks warm.

*by P***R on 11 January 2026*

A truly outstanding little flask. I have the 900ml and the 500ml both are exceptional and keep everything very hot for 24 hours, I use the small one for soups and all sorts. Great value for money and excellent performance. Well worth buying.
