Thermos Stainless King Raspberry Pink Flask (1.2L) 24h Hot | 24h Cold

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.

I just bought it recently and wondering why I didn’t purchase it earlier? I boiled water and filled up this flask at 8am and used it last at 8pm. Water was still boiling hot. This flask is great if you are looking for a flask that will keep water at 70° to make baby formula. Pouring it in milk bottle is also very safe and comfortable with no worry of spilling due to the design. I would probably give this as a gift to someone at a baby shower as it will make the night feeds soo much easier.

I've been using this Thermos for a while now and I'm really impressed. It keeps my tea hot for hours, doesn't leak, and the 1.2L size is perfect for work or day trips. The cranberry red colour looks great and the build quality feels excellent. Definitely a product I would recommend!

Works well. The only downside is it doesn’t keep things hot for 24 hours like stated, 12 hours Max’s. Still better than all the others flasks I have purchased that only kept things warm for around 6 hours.

Its well made, keeps tea warm over my 12 hour shifts no problem. Herbal tea ( no cold milk added ) remains very hot over the 12 hours, too hot to drink with out letting it cool down, even near the end of my shift. So well pleased. The handle does rattle a bit as its metal on metal, but it seems strong. I think it will last and be durable.

Got this as I broke my old pump top one, not a Stanley, it fell off the seat when I opened the door. So far so good, iv been using it just for cold water at the moment and it seems to be fine, iv not bothered with putting ice in but it definitely keeps it cool, I just fill from the tap.excellent so far

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!

Termo muy bueno, mantiene la temperatura durante mucho tiempo. estoy contenta

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.
