BuiltDouble Wall Vacuum Insulated Food Flask for Hot and Cold Foods, Stainless Steel, Grey, 490 ml

I’ve used this twice with some food for lunch- breakfast and preheated the flask as instructed. Mid-morning, I have gone to my bag and the outside of the flask is warm, as is the bottom of my bag. I am not entirely convinced that lunch will be warm! It looks good but it’s going back, the food lost all its heat within a couple of hours!

Iv used this product twice and dont bother anymore. Instructions were followed to pre heat container with boiling water, hot food put in at 8am and is cold by 12:00pm (lunch time) no good for what I intended to use it for. Disappointed.

Gives the impression its American. It was made in China. We are now in an age where i would rather not buy anything form China. Bad call : Update the stopper has broken away from the top and is pretty useless. This is what i thought was going to happen with something made in China. Tesco do a 500ml for less money take a gamble with theirs. Update it lasted 12 months then the top inner threaded part detached from the top.

This is amazing. I actually find the food is too hot, possibly hotter than when it went in. Some sort of thermal magic. Use it for porridge in the mornings when I take my dog for a walk. We have a family walk/breakfast before school/work. Best start to all days.

I got this for my 4 year old daughter to take warm meals to school. With a pre heat with boiling water for 5 minutes it keeps the food warm (she tells me). The wide neck means she can eat from it fairly easily and she loves the colours. She needs the lunchtime staff to help her open it but that’s to be expected as she is only 4. I would buy again.
