Thermos - Stainless King Raspberry Travel Flask (1.2L) - Premium Leak Proof I...

I bought this Thermos Stainless King travel flask mainly for preparing formula for my baby while out, after seeing posts online mentioning that it can keep water above 70°C for long periods throughout the day. The quality feels excellent and the stainless steel design feels very durable and well made. The matte black finish also gives it a sleek look while providing a nice grip in the hand. The heat retention is definitely the standout feature. It keeps the water hot for hours, which makes it extremely convenient when travelling or spending long periods out of the house with a baby. Knowing the water stays at a suitable temperature for formula preparation gives extra peace of mind. It seals very securely and has been completely leak proof for me so far, which is especially important when carrying it in changing bags or while travelling. It’s also easy to pour and drink from, and the overall size makes it portable enough for everyday use without feeling bulky. Another plus is that it’s straightforward to clean, I have purchased the OXO bottle cleaning brush for it, which makes cleaning much more convenient. Overall, a very practical and reliable flask that feels worth the investment.

Usually buy the other well known product but pricing is ridiculous. Opted for good old,dependable Thermos. Great product. Little touches like the lid is angled for easier grip but also indicates the easy pour vents. Comfortable handle and obviously the flask keeps everything either hot or cold for the length of time that I require it. Can’t fault it.

Best flask I have had so far. As a truck driver it’s always handy for me to have a good flask or stove for hot drinks This flask is the best I’ve purchased to date. I filled the flask at around 18:30 with boiling hot water. The water was still very hot at 4am. So I managed to have 3-4 hot drinks through the night. Even more impressive, I went to bed after my night shift. When I emptied the flask around 14:00 the following day. The remaining water still felt hot. I do have the flask in the truck. Maybe it would not stay as hot for long for an outside worker but I still recommend as it is a good size, secure lid, good carry handle and quick and easy to unscrew and pour a hot drink

First time I brought a flask. Feels like it has been built to last a life time. Keeps thinks piping hot the whole day. Great flask. Highly recommend. Haven't experienced any leaks and can fit a good days worth of tea/coffee etc. Handle feels very sturdy to carry the weight off it. Don't think I would buy any other one other then this brand from now on.

A great flask for days out and no worries if you drop it. If however you intend to go hiking with it.. the rattly handle will drive you insane as you walk along. I ended up tying a bag around it and stuffing tissue paper into the handle rings just to shut the thing up. My other 'quibble' would be that it only comes with one cup despite it holding 1.2 litres of brew.. what were the designers thinking? . Its a nice colour though and serves me well for work.

Absolutely love my Thermos Flask - great size, holds alot of fluid and keeps it hot/cold all day!! Added bonus of handle and cup (dont really use the cup, but its good to have), super sturdy and very easy to use.

I bought this Thermos Stainless King mainly for long work days and trips where I wanted properly hot tea without paying service station prices for disappointing coffee. After using it regularly, I can honestly say this thing takes temperature retention very seriously. The first thing that impressed me was just how long it keeps drinks hot. I made tea early in the morning, forgot about it for hours, and it was still properly hot later in the day, not “technically warm if we lower expectations,” but genuinely hot enough to enjoy properly. Cold drinks hold up equally well too. Filled it with iced water during warmer weather and still had ice hanging around much later than expected. The insulation on this flask is great! Build quality feels excellent as well. It has that reassuring “solid chunk of stainless steel” feel that makes you think it could survive being dropped down a hill and still come back asking for more tea. Definitely feels durable enough for everyday use, commuting, travel, or outdoor trips. The twist pour stopper is also far more convenient than I expected. Being able to pour without fully removing the lid is one of those small features that becomes genuinely useful once you start using it regularly. Less heat escapes, less chance of spills, and less fumbling around when half awake in the morning. The built in cup is decent too. Simple, sturdy, and does the job well enough for tea or coffee breaks on the go. It’s also surprisingly comfortable to hold considering it’s attached to what is essentially a giant insulated steel cylinder. Capacity wise, 1.2L is excellent if you drink a lot throughout the day. It’s enough for multiple large cups without constantly refilling. The trade off is that it’s definitely not a tiny lightweight flask. When full, this thing has some heft to it. Not ridiculous, but you’ll notice it in a backpack. Leak proof performance has been great so far as well. I’ve carried it horizontally in bags without any unpleasant surprises, which already puts it ahead of several “premium” travel mugs I’ve owned. The red finish also looks really nice in person. Bright enough to stand out without looking cheap or overly flashy. Overall, this is an excellent flask if you want serious heat retention, durability, and large capacity. Reliable, practical, and built to last. The kind of product you buy once and end up using for years mainly because it stubbornly refuses to stop working properly.

This keeps hot drinks very hot til the end of the working day, 8-10 hours and still steaming. I also have the “food” flask for soup. Essential kit if you work outside in the sea in all weather.

+ hält warm was warm ist + qualitativ sehr hochwertig verarbeitet + optisch ein echter Hingucker - der Henkel ist echt gewöhnungsbedürftig Fazit: alles in allem eine super Kanne, die hält was sie verspricht; für den Henkel gibt es keinen Abzug, da nach über 24h der Tee immer noch heiß ist!

متينه وجوده ممتازة احتفظت بحرارة الماء حتى درجة ٧٠ مئوية تقريبا ٦ ساعات ، طبعا التجربة كانت في بداية سبتمبر، وننتظر تجربتها في فصل الشتاء

Très joli Belle capacite Maintient bien au chaud même en hiver Nettoyage facile

Nothing to dislike about this thermos. It keeps my tea hot all day, pours great and is super easy to hold and pick up by its cool retro handle. It’s a big one, but not too big - holds around three big mugs of tea which is about all I need through the day. I was worried that the stainless steel interior would change the tea flavor, but it doesn’t at all. Very happy with this purchase.

molto robusto, tiene bene il calore, il tappo a vite non e' comodissimo per versare senza svitarlo tutto (si rischia di schizzare un po' in giro), e la maniglia in metallo e' un po' rumorosa se sbatte, ma sono dettagli trascurabili.
