Thermos - Stainless King Red Travel Flask (1.2L) - Premium Leak Proof Insulated Tea & Coffee Flask for Hot & Cold Drinks, Built-in Cup, Twist-Pour Stopper, BPA-Free, Durable Steel

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.

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.

Took with me to climb Snowden, easily poured 5 decent sized cups of Tea. Retained the heat very well, was still steaming a good 10 hours after making. Great bit of kit - recommend. Easy to pour, twist top so less less likely to break unlike previous other push top ones i’ve bought.

Keeps liquid hot for an exceptionally long time. No leaks and love the design and large capacity. Easy to take around when out and about.

Nice flask. Keeps the heat well. Good seal. Handle is noisy and clunky. Heavy. Only thing I don’t like is it’s not great for a steady straight stream, ends up splishysplashy half the time which isn’t great if you are trying to pour into something like a hot water bottle or something that isn’t a big cup opening

I bought this expecting it to be decent, but it’s genuinely blown me away. The heat retention is outstanding. I’ve filled it with tea at around 6am, forgotten about it, and then come back the next day at about 8am to find it still hot enough for a proper cup of tea. That alone makes it worth it. The built-in cup in the lid is a really convenient feature and makes it easy to use on the go without needing anything extra. It’s a simple touch, but very practical. The handle is a little fiddly at times, but it does the job and isn’t a major issue once you get used to it. In terms of value, I think the 1.2L size hits a great balance between capacity and price. It’s big enough to last all day (and then some), without feeling excess

Lovely colour brilliant quality, stays hot for many hours! It’s the best out there!

There is only one name when it comes to flasks, Thermos. Lovely colour.Bought this for my wife and she loves the colour. Also as expected, keeps hot coffee hot for the 12 hours she needs it. Buy a non bra ded flask and you will buy a decent brand one shortly after. Buy a Tbermos and you will have it for years. My one has been in daily use now for 10+ years and is keeping my drinks hot as good as the day I bought it. The flask has been dented, dropped and scratched but still performs as good as new. Absolutely recommended. Reasonable price for years of use.

perfeita

+ 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

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.

Perfetto per portare con se acqua calda in montagna, all'arrivo ci si può creare il te, caldo o freddo che si voglia. Ricordarsi di preriscaldare o raffreddare l'interno del contenitore, altrimenti il liquido perderà la propria temperatura subito
