I put water from a one cup machine (not exactly boiling water from them) at 7pm. Opened at 9am and the water seemed hotter than when it went in!!. I’m really impressed. I’ve had loads of the “best!” brand flasks and this is up with the best of them. I’m really pleased with it. Great buy.

Tested the flask before took it out, I am glad I did, filled it with hot tea at 7.45 am, last cup poured was at 14.40 which couldn't drink as lukewarm . that is 7 hrs, last cup being lukewarm would say mine only lasted for 6 hrs, which is rubbish as need one for 12hrs...would not recommend!

I bought this flask because of the reviews and having several flasks that don’t hold the heat for long... well this flask is wonderful!! It has kept my coffee HOT... not lukewarm for 15.. yes..15 HOURS!!! Amazing! Highly recommended!!

Read some reviews beforehand that said this was a better flask than some more expensive ones so I got it for a trip to Keswick in the Lake District to keep coffee and soups hot on hikes. Was so impressed, not only did it store a litre, but it kept things hot and cold for 6 hours+ and the outer metal never got hot at all to hold. Cut the up to use on it, and so cheap, easy to clean. 10/10!!

I've read other reviews regarding this flask stating how well it keeps boiling liquids hot. I must have received a faulty flask because after around 3hrs, my coffee is Luke warm!! I work as a HGV driver, on the road long hours, this flask is no good for me whatsoever!!
