Verified Purchase(What is this?)
This review is from: Thermos Everyday Food Jar, Stainless Steel, 0.5 Litre (Kitchen & Home)
I love this bit of kit and don't really understand what the 1/2 star reviewers are talking about.
I simply follow the instructions that were provided with the flask and it keeps things lovely and hot for hours.
Generally I'll pre-heat the flask with boiling water straight from the kettle and clamp on the lid for 10/15 minutes, then, just before I'm leaving the house I'll microwave my soup, or pasta, or rice, or leftovers, or whatever until they are piping hot, unscrew the lid of the flask, tip away the hot water then tip straight in the piping hot food and clamp on the lid.
This last part of the process, the filling and final closing, generally happens at around 8am just as I am about to leave the house for the day. I generally eat at 1330/1400 ish and the food is still lovely and hot - I don't mean warm, I mean hot, hot "that you have to blow it to cool it before eating it" hot.
I have been known to eat as late as 1445 and again it is still hot.
I think the trick is; to ensure you pre-heat, make sure the food you're adding is piping hot, and don't leave the flask empty at any time between the pre-heat and the actual filling with food.
I love mine.
