Well made food flask with generous capacity
I bought this Thermos Stainless King Food Flask for the young one’s lunches and it has been brilliant, well worth the cost. The 710 ml capacity is generous and easily holds a good portion of soup, stew, pasta or a hearty lunch, so there is plenty of space for a proper meal rather than a snack-sized portion. Build quality is exactly what you would expect from Thermos. It is well made and feels robust. The stainless steel construction with the gun metal finish looks smart and holds up well to daily use without showing scratches or wear. The lid screws on securely and seals well, which is reassuring when it is being carried in a school bag. Heat retention is excellent. I preheat it with hot water from the kettle for around 10–15 minutes to warm the flask properly, then add the food. Using it this way, the contents stay piping hot for hours, which makes a real difference. The wide mouth makes it easy to eat straight from the flask with a spoon and also makes cleaning much simpler. It also works well for cold foods or drinks if needed, and there is no condensation on the outside, so bags stay dry. I am very happy with this flask and, as long as the young one does not lose it, it should last for many years to come.

Great for Healthy Homemade Pot Noodles
Love this wide mouth food thermos and am so glad I paid for a good brand as it works so efficiently. Mainly using it for "instant" ish noodle bowls. I pop in my home made broth powder, dehydrated veg and dehydrated egg pasta noodles, add boiling water and leave it for about 10 to 15 mins giving it a shake from time to time. I then pour the contentd which are now perfectly cooked, into a bowl of I'm at home or eat them directly out of the flask if I'm in the go. The wide mouth makes it easy to fill, pour and clean. It goes in the dishwasher but to be honest, it's so easy to wash straight after use that I will probably just hand wash. Portable and when filled with soup it was still very hot after 4 hours. Great quality.

Durable, fit for purpose, longlasting &:high quality
I purchased my twin grandchildren 0.40 L Thermos food flasks when they started secondary school. The flasks are still going strong, but larger upgrades were needed as the grandchildren are now at college & require a more substantial meal. As with the earlier version, the 0.70 L flask is perfect. I filll the flasks with boiling water for as long as possible (sometimes overnight) prior to putting their meal in. 5.5 hours later, the food is still piping hot. A few days ago, my granddaughter didn't get chance to eat lunch & ate it in the car on the way home. 9.5 hours after filling the flask & the meal remained piping hot. The key to keeping food hot is to adequately pre-heat the flask & fill to the top. The larger size weighs much the same as the smaller, older model The flask doesn't leak. I've purchased many Thermos products over the years & can hand on heart say that I've never experienced a problem with any of the products from this company. They're my go to brand & I recommend them.

Quality, no included spoon.
A great food flask, keeps my food warm for at least 8 hours. Personally I use it for pasta, for work lunches. Was disappointed to find that this did not include a spoon in the larger size, despite the AI assistant telling me it does. Good value for money, the durability and build of the item is polished and will surely keep for a long time. It is quite a weighty product so keep that in mind if intended for long treks with a flask full of food. It’s easy enough to clean, but may be harder if one does not own a dish brush.

Nice wide neck. Dishwasher safe too!
Bought for my husband who works 13hr shifts in A&E. So usually his lunch break is about 6hrs after he starts. Has a nice wide neck so easy to fill with things like soup or rice pudding and does not spill. Does keep food warm but not hot. He was perfectly happy with it and certainly still warm enough to eat and enjoy his soup. But better a few degrees warmer.

Keeps a casserole piping hot, make sure to fill it to the top tho.
I bought this especially to put hot food in while I'm doing EDF Sunday Saver from Monday to Friday, where you dont use much electric between 4 and 7pm. I usually manage to 'earn' about 12 hours the following Sunday by switching everything off practically and eating my main meal of the day at lunchtime instead of in the evening. I can't adjust to eating midday instead of evening for some reason so thought I'd buy a food flask so I can make the food midday then put it in the Thermos so I could eat it in the evening. Then at lunchtime just have a snack or do a bit of fridge grazing. It seems to wrok for me. So I needed a reliable thermos that had a big enough neck to put the food in it and then keep it hot for as long as possible. So far it's come out well in the tests, soup, pasta dishes etc. I'm pleased to report it keeps whatever I put in there very hot as if I'd just made it so it's ideal. As for the size, I wasnt sure which to get, the 500 or the 750ml version. I didn't think the smaller one would be any good for me as it woulldn't hold enough food, so I went for the bigger one. I'm so glad I did as this one as the 500ml one would have been tiny, and I've had needed a pair to make one decent meal of beef stew and dumplings or chilli etc. I've found if you fill it right to the top almost it will keep the food hotter too. As long as you can get the lid on without the contents squeezing through the screw thread and making a mess. So yes I'd recommend the bigger one for one person who has a normal appetite and the smaller one for maybe someone who's always watching their weight and eats like a bird.

Ottimo prodotto
Il thermos è spettacolare! L’ho comprato per mio marito che è costretto per motivi di lavoro, a pranzare sempre fuori. Cercavo un prodotto che mi consentisse di fargli portare un pasto sano e mangiarlo caldo! E non potevo scegliere di meglio. Preparo il cibo la mattina alle 6 e alle 14 (ma abbiamo constatato che arriva anche oltre) resta caldissimo. Le zuppe addirittura restano bollenti. Se si ha l’accortezza di riempirlo per 10 minuti con acqua bollente e poi una volta svuotato inserire il cibo caldo, la durata è assicurata! Se preparate la pasta consiglio di scolarla molto tempo prima dei minuti indicati perché mantenendo il calore, la pasta rischia di scuocersi. Lo consiglio vivamente.

Hermético y muy aislante
Es un termo muy hermético que mantiene las temperaturas muy muy bien. En mi caso lo he utilizado con alimentos caliente e independientemente de que fueran más líquidos (como pures o sopas) o sólidos, ha mantenido la temperatura perfectamente. Es fácil de limpiar y no tiene peligro de derramar nada estando cerrado. Antes de escogerlo, tener en cuenta que la boca del termo no es muy ancha, lo que la hace un poco más incómoda que otras para comer desde ella. Pero tiene una capacidad muy buena para una muy buena ración de comida, y aunque no totalmente cómoda se puede comer desde ella sin problemas

Perfekt!
Die Flasche hat eine perfekte Größe, hält 100 %ig dicht und richtig lange heiß. Ich mache mir am Vortag so gegen 18 Uhr ein Gericht für das Mittagessen auf Arbeit und habe dann gegen 12 Uhr noch richtig heißes Essen. Das Gefäß ist gut zu säubern, lediglich die Gummidichtung nimmt schnell Farbe und Geruch der Mahlzeit an. Auch zum Wandern super geeignet!
