Stainless King Copper Travel Tumbler

The Thermos King Travel Tumbler has quickly become my go-to travel mug. It keeps coffee hot for several hours and cold drinks stay chilled for much longer than expected. The stainless steel construction feels durable and well made, and the lid seals securely with no leaks in my bag. It’s comfortable to hold, fits most car cup holders, and is easy to clean. If you want a reliable travel tumbler that actually maintains temperature and doesn’t leak, this is an excellent choice.

I’ve been using my Thermos tumbler for about a year now, and it’s by far the best I’ve ever owned! I had been using Bodum travel cup until then, but needed one that was fully leakproof and this Thermos one is incredible: I can put it in my handbag when it’s full, and even if it falls in my bag, not one drop of coffee spills! I’ve also wanted a bigger one to fill a grande size at Starbucks and this does the job perfectly. I struggled a bit to deep clean the top at the start but since I’ve done it the first time it’s now super easy. It keeps my coffee warm for hours, which is just what I needed for when I sit at Starbucks with my book for a couple of hours. It’s a bit bulky but fits perfectly in a mid-size tote bag. I will definitely buy another one when this one gets tired, but I feel like I’ll be able to use it for years as it’s still in perfect condition after a year or daily use. I hesitated to purchase at first just because of the price point, but it’s 100% worth it (and repaid by the discounts I get for my coffee every time I use it in shops!). Cannot recommend enough!

I’ve been quite obsessive about finding the perfect thermos flask to keep my drinks at the perfect temperature, whether it’s hot or cold. After much searching, I stumbled upon this flask after a recommendation from a friend and it checks all the boxes for me. This thermos flask has exceeded my expectations in every way, and I can confidently say it’s the best one I’ve ever had. One of the standout features of this flask is its insulating properties. I now find with my hot drinks like tea or coffee I need to let them cool down before popping the lid on as this just retains the temperature for so long. Not only does it hold the right amount of liquid, but it also boasts a leak-proof design. I can carry it in my bag or place it on my desk without worrying about leaks. When it comes to maintaining the desired temperature, this flask truly excels. Whether I want to keep my coffee piping hot during a long commute or enjoy a refreshing cold drink on a hot day, this thermos flask consistently delivers. The insulation is incredibly effective, keeping my drinks at the perfect temperature for hours. The build quality ensure that it can withstand everyday use and the occasional mishap. It’s a reliable and resilient companion. This thermos flask has exceeded my expectations in every aspect and I’d recommend it to anyone.

I bought this because I'm involved in hour-length sports events in the control room, where I simply cannot get up and go for a tea. I was looking for a good size, nice looking travel mug that wouldn't spill if knocked over. And that's what I received. I don't trust sipping hot drinks with these kinds of mugs so fully open the lid. The open/close valve I use just to relieve pressure before opening. Hot drinks stay hot for hours. This is kind of what I'd expect, except they're always too hot when I first prepare them, so have to add loads of milk to bring temperature down. The capacity is good although I learned to leave space for the part of the lid that sinks into the cup. First time, it caused a spillage as I'd over-filled it. Described as "gun metal" the images just looked black. However it's a really nice dark grey which I was hoping for. I'm happy with it.

Great flask and really does keep your drink warm throughout the day

Really works keep hot drinks hot for ages.

Hat die Heißgetränke auch im Winter Schön lange warm gehalten, Stundenangaben kannn ich nicht machen da es immer nach spätestens 2 Stunden leer war, aber in dem Zeitfenster keine merkliche Temperaturveränderung. Verschluss ist dicht. Öffnen und Schließen geht gut, Flüssigkeitsabgabe ist angenehm, gut zu reinigen. Außerdem sieht er super aus.

Ideal para llevar el desayuno al trabajo, la capacidad es como un vaso y medio grande

Ottima tenuta! Mantiene caldo il mio caffè e non rovescia nemmeno una goccia!

Es super bonito i cumple 100% con su prometido... Incluso el color es mas bonito en realidad!! Volvere a comprar más de esta marca sin duda porque estoy super contenta!!

It looks amazing and keeps my coffee hot for long time!
