Q & As

Rated 4 out of 5 by 7 reviewers.
Rated 5 out of 5 by Really useful This flask is the ideal size for putting in a holdall when out and about on a cold day! 04 February 2015
Rated 5 out of 5 by 8 month and still going I had this for 8 months for keeping the water warm/hot for a baby feed. So far its been good it has hold its temperature up to 12 hours. 09 September 2014
Rated 2 out of 5 by Almost not quite The product seemed promising and did keep the drink hot for a couple of hours. Disappointed that the insulated cup isn't quite insulated and is too hot to hold when there is drink inside. It is just day one... Hope it stays sturdy.. 10 July 2013
Rated 5 out of 5 by very handy and practical I take this flask everywhere and it keeps fluids very warm / hot for at least 5 hours. If anyone is thinking of buying a flask, I would most definately recommend this product. The tip of cleaning the flask in hot water then pouring your desired drink in it keeps the fluids hot much longer too, 03 December 2012
Rated 1 out of 5 by Waste of Money I bought this as I thought it was the perfect size to take to work. I had this approx. 6 weeks and used it only a handleful of times before the vacuum 'broke' rendering it useless. Waste of money. 13 November 2012
Rated 5 out of 5 by Perfect After purchasing the Anorak version which leaked and did not keep the contents hot for long, a replacement was sought. I should have bought this all along! Great size, robust, well fitting lid and top - no leaks on my bumpy train journey to work. Keeps the contents hot for ages, drinkable all morning in fact. I am so pleased - highly recommended. 02 August 2012
