Customers say

Customers find the thermos effective for school lunches and appreciate its size, being small enough to fit in a lunch bag while holding the right amount for a child's meal. The product is well-made, easy to open even for young children, and easy to clean, with one customer noting it keeps frozen fruit frozen for a long time. While some customers consider it worth the money, others find it rather pricey.

I now have 4 of these !!!!
Reviewed in the United Kingdom on 3 March 2014
Colour Name: BlueVerified Purchase
I was sceptical as they are expensive for a small flask but a friend reccommended this type and, as I have tried others which are either too big for or don't keep food hot all morning, I thought I would give these a go. Initially I bought 2 of these so the children could have hot meals at school for a change without the risk of 'today's special' in the canteen being on the 'don't like' list.

I always pre-heat them with boiling water at 7am for 10 mins while I heat the food and let it boil well so that I know it is as hot as i can get it. In it goes, full to the brim and lids on. The 10 year old has lunch at 12, the 14 year old at 1pm. They both report that at lunchtime(after 5 and 6 hours) the food is hot, though not burning. Pretty impressive!! (incidentally i wondered if the lid would be difficult to open but the 10 year old reports it not so... bet he wouldn't have managed it at 5 though!!)

They have rapidly become my receptical of choice for reheated dinner left overs (you know those times when there is not enough bolognaise left for another dinner but too much for the bin...add some more veg and tomato sauce and lunch is made!!)

Then my husband started using one to take porridge on days when i wasn't using them for the children. Then when he has to work late he dicided to take a hot lunch and a cold dinner. The tub is a smaller portion than he would normally eat but works well with a bread roll and banana with it.

Then we took hot lunches for the kids on a satuday hike in the snow and they scoffed them mercilesly while we only had a flask of hot tea with our sandwiches. So i bought 2 more flasks.

I find they work best with food that is slightly more liquid than normal (eg add some extra tomato sauce to bolognaise) and chopped small so there are no air gaps in the pot (use small pasta shapes and chop carrotts into dice rather than pennies!!)

Our favourite 'hot pot meals' are
bolognaise with space pasta (some supermarkets stock the shapes!)
chicken and vegetable casserole
sausage, pasta and veg in tomato sauce
creamy chicken pasta
sausages and baked beans
soup (i tend to put in a really thick one)

they are also the right size for those mug sized packets past like mugshots. Just preheat the jar, add the packet, fill with boiling water stir well and they are soft and have absorbed the water at lunchtime... handy for camping

I have steered clear of rice in it... not sure about the food safety implications keeping reheated rice hot for 6 hours ???

yes thay are expensive but...
It is cheaper to buy vegetables than fruit so a carrot & sweetcorn in the hot pot is a cheaper way to 5 a day in the packed lunch than an apple and grapes!!
Dinner left overs are no longer wasted!
If they take the place of buying school lunches and more significantly motorway service station meals they pay for themselves very quickly!!

Great for a 4y
Reviewed in the United Kingdom on 14 October 2024
Colour Name: BlueVerified Purchase
My son has used it for a month now, and it’s a great size for his lunch. I don’t send very liquid soups as I don’t think it would work as it would just go everywhere and it’s not the right angle for him to eat it with a spoon, but I have sent lots of other things and he eats it all so he must like it. Can’t rate how long it keeps it warm for, as I’m not there at lunch time but tbh my son doesn’t like very hot food anyway. It’s easy to clean, the rubber comes out if you need to clean it a bit more. It has a space on the lid that’s hard to reach, but with a little brush you can do it.

Keeps food warm, no leakages!
Reviewed in the United Kingdom on 15 February 2021
Colour Name: BlueVerified Purchase
I was looking for a small, good quality flask for my 6 year old son to fill with nutritious meals (mainly left overs from the night before!) to take to school with him, as an alternative to cheese sandwiches and ham sandwiches at lunch times.

I purchased this flask together with a pink version for my 9 year old daughter and they have been fantastic! In fact since my daughter started using this, many of her peers started to take flasks to school too (prior to lockdown!) .

They are just the right size for lunch-I fill each one almost to the top with left over chilli, lasagne, sausage pasta etc and on most occasions nothing is left.

I’ve never known these to leak and they are easy enough for the children to open themselves.

They tell me that food is still warm at 11.30am when they have their lunch in school. I heat these up at around 7.45am, as we leave for school at 8. A tip my friend gave me was to add boiled water to the flask for ten minutes, empty then add the heated food - always seems to work.

These are also very quick and easy to clean. Instructions say not to put in the dishwasher, so I rinse these with warm soapy water.

Piccolo ed efficace.
Reviewed in Italy on 18 February 2014
Colour Name: BlueVerified Purchase
Thermos piccolino e leggero ma robusto e resistente. Conserva il caldo fino a 5 ore (scarse) e il freddo fino a 7 ore (scarse). Importante per aumentare la durata del mantenimento a temperatura, è riempirlo di acqua fredda o calda (a seconda se dovrà contenere cibi freddi o caldi) per circa 3 minuti. Acqua calda o fredda da rubinetto, non serve raffreddarla o scaldarla ulteriormente.

Il thermos ha un volume interno di 290 ml, da poter utilizzare per gli alimenti. Corpo in metallo colorato ed estremità in plastica con buone finiture.

Leggevo da recensioni di altri utenti che è considerato troppo piccolo.. ma dipende evidentemente dalle esigenze.
Io lo metto nella sacca della palestra, è quindi ottimo per misure esterne contenute, e per la resistenza e lo riempo con un veloce pasto post allenamento che consumo in ufficio. Per me è perfetto, contiene una porzione (la mia è circa 80/90 gr) di riso, o di pasta, o una porzione di minestrone (circa 200gr) o di insalata di frutta. Non mi serve di piu.

L'apertura è molto ampia, e quasi non presenta un "collo" , questa caratteristica di forma, assieme al fatto che il contenitore è abbastanza basso (115mm), lo rende molto comodo per poter infilare posate a raccogliere fin le ultime briciole/gocce

(io consiglio posate di plastica per non graffiare l' interno, anche se è comunque di metallo abbastanza resistente.

Inoltre, cosa per me importante, si presenta bene, ha un bel colore e buone finiture.
E' un oggetto che puo essere lasciato sul tavolo di lavoro senza vedere o odorare cibo, cosa che in uno studio/ufficio elegante è decisamente da evitare.

Queste considerazioni, in aggiunta al prezzo estremamente basso (visto il poco materiale usato) lo rendono per me IDEALE.
Molto consigliato a chi ha quindi esigenze simili alle mie.
