Milton Vacuum Flask for Hot Drink 500 ml (16 oz), Stainless Steel Double Walled Insulated Water Bottle for 24 Hour Hot and Cold Drinks, Leak Proof, BPA Free, Thermosteel Flip Lid

I bought this flask mainly to keep hot water ready for my baby’s night feeds, and it works perfectly. The water stays hot for many hours, which makes it very convenient to prepare milk quickly during the night without going to the kitchen. The build quality feels strong and the lid seals tightly, so there are no leaks. The 1-litre size is great and lasts the whole night. Overall, a very useful and reliable flask—highly recommended for parents with babies. 👶🍼

Perfect flask. Keeps drinks hot or cold for many hours. Approx 6 drinks from it. Easy to use. Good value for money.

We’ve been using the Milton 1 Litre Vacuum Flask regularly for both hot drinks and cold drinks. We had a smaller size flask but had to upgrade it for our trip to Europe. We mainly used it for storing hot water and coffee, it performed consistently well during the trip. The build quality is solid—it feels sturdy in hand, it's not light, and has a practical design. I think the stainless steel body is resistant to dents and scratches, and the lid doubles as a cup, which is a convenient touch. The flask is easy to open and close, and the leak-proof seal has held up well over time. Also, the flask comes with a pouch so it's very easy to carry around. The colour is grey and looked like a standard flask. In terms of performance, it kept drinks hot for 12+ hours, which is ideal for day trips. We’ve tested it with boiling water in the morning, and it’s still hot by late afternoon. It also works well for keeping cold drinks chilled, making it versatile across seasons. Cleaning is straightforward—wide enough opening for a bottle brush, but because it's quite long and a little difficult to clean the bottom of the flask. The 1-litre capacity is generous without being bulky, striking a good balance between portability and volume.

I can’t express how much I love my Milton Vacuum Flask. As a busy parent, having a hot drink ready whenever I need it feels like a little luxury in the middle of chaos. This flask keeps my tea and coffee piping hot for hours—seriously, I’ve come back after a long outing and it’s still warm. It’s such a relief on those cold mornings or during late-night feeds when I just need that comforting sip. The size is perfect—500 ml is enough to keep me going without being bulky. It’s lightweight, easy to carry, and the design feels sturdy and reliable. Plus, no leaks! I can toss it in my bag without worrying about spills. Honestly, this flask has become my little lifesaver. If you’re always on the go and crave that hot drink to keep you sane, this is a must-have. It’s simple, practical, and makes life just a bit easier—and that means everything.

Excellent product. Keeps fluids hot for over 12hrs. I had to come back to review to assist anyone looking for a reliable vacuum flask. With so many options available its not always easy to choose the right one. I would buy again and highly recommend it.

Best flask I’ve found. Didnt realise how big it was but does what it says unlike any other I’ve tried. I use it for the boiled water for my babies bottles and when emptying it after ive finished using the water is still boiling hot.

I use a flask daily, and refill it 2-3 times each day. So far, this Milton flask is performing exceptionally well. It is large, well made, and keeps my drinks hot for longer than any other flask I have purchased in this price range. I have left some coffee in a flask for 12 hours, and it is still warm. The body of the flask, has been easy to clean, and the inside hasn't got coated in tea stains, which most flasks tend to do. The sealing cap has a built-in pouring spout which seems robust enough, to make me think it might last a while. Overall, it seem very good value for money.

​I bought this thermos to prepare my daughter's formula. ​I only used it for boiling water... I haven’t used it for any other drinks. ​It saved me from boiling water all night because it keeps the water hot, at least during the nighttime. ​I was hesitant because of the negative reviews, but after trying it, I will be honest: ​It keeps boiling water ((not hot water )) for only 10 hours. For the first 8 hours, the water is hot. After that, for about 2 hours, the water becomes warm, not very hot. ​Does it keep water hot for 24 hours? The answer is no. ​Does it leak? No. ​If you wash the lid thoroughly under running water and put it back, you might see a few drops when you flip the bottle—this is from washing the lid, not a leak from the inside. ​It’s possible that the reviews mentioning leaks were due to the product being dropped or damaged during shipping, and they have the right to return it. ​I noticed most people said the lid/cup fell apart. It seems they were using it for drinks. I never used it for anything but water. I believe the cup might not handle very hot liquids, which causes it to separate. If your goal is to use the cup for drinking, it’s not suitable. ​Regarding the included carrying bag, it feels cheaply made. Honestly, I haven’t used it.

The bottle has stopped keeping warm after using for 10 days. Very poor quality.

Hält Heißwasser mindesten 12 Stunden, Kaffegetränk bisschen weniger. - das besser als andere

Really good for the price!

I myself checked how much time I can keep the temperature fairly high temperature. I use boil water to check.As I realize, even though it is not always at 100° c after 12 hours. I just realized still it is hot enough for a hot coffee. But after 24 hours it is not that much hot during the winter season under 10° c of room temperature. If you pour a hard boiled water at night in the early morning, you will be able to make a hot coffee by using this water in this therm of flask. With my experience I can recommend this bottle for 12 hours of time duration.

Very nice thermosteel water bottle this brand thermal bootles very good. This bootle is very useful, it works for a long time.
