Q & As

Rated 4.5 out of 5 by 10 reviewers.
Rated 4 out of 5 by Does the job Purchased this flask for picnic lunches and has been used a lot. We use it for hot water for making tea and it certainly keeps the water boiling hot for several hours. 27 October 2015
Rated 5 out of 5 by Just what I needed Started new job, working outdoors and only have half an hour to grab lunch so perfect for quick tea break and lunchtime brew. Light and liquid stays hot all morning. 06 October 2015
Rated 5 out of 5 by Does what it should I had not bought a flask in years so I was very pleased to find this one is strong, light and keeps water hot for ages. 18 August 2015
Rated 5 out of 5 by Still the Best You still can't beat the original and best makers of flasks. Like the names Hoover or Kleenex, the name Thermos has become synonymous with its function. 31 March 2015
Rated 5 out of 5 by Great product Delighted with this purchase The flask works very efficiently. 09 December 2014
Rated 5 out of 5 by Very good quality ! It's great product! Very useful ! Bought few different flask before non of them is as good as this one really good! 18 November 2014
Rated 2 out of 5 Brilliant to start with but leaking after only a few months... I bought this to use for my daughter's bottles to avoid boiling the kettle multiple times a day for a small amount of water - after only 5 months of using it it has started leaking badly unless it is kept upright. It's mostly kept upright at home anyway but I'm now unable to take it out unless i can guarantee that it won't be tilted or fall over. I've given it 2 stars as up until now it has been brilliant and does what it says on the tin keeping water boiling hot (or close to) for 12 hours. Disappointed as it's quite an expensive flask and would have hoped for it to last longer 10 November 2014
Rated 5 out of 5 by Nice and hot This is the 2nd Thermos flask I have purchased as my old one had seen better days. It kept my drink hot all day and the cup is better to drink out of, as the rim is smoother compared to the previous Thermos flask I had. 11 May 2014
