This Milton 500 ml vacuum flask is an excellent everyday bottle for keeping drinks hot or cold.

The lid screws on securely and doubles as a cup, which is a nice practical touch. It’s lightweight, easy to clean and comfortable to hold. The sleek design looks smart, and the 500 ml capacity is just right — not too big, not too small. If you’re looking for a reliable, well‑insulated and long‑lasting flask, this Milton bottle is a great choice — perfect for hot drinks on the go and excellent 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.

It does its job well. I made coffee at 6:00 PM, and by 10:00 AM the next day it was still warm, though no longer hot. The thermos is metal and feels durable. Overall, the product meets my expectations and seems like it will last for years.

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. 👶🍼

Really good flask , it too heavy , easy to clean .

Fantastic! It does exactly what it says on the description! I need it new flask for a quite long journey by car and this one kept my tea hot for very long time !!! As more than 10 hrs ! After 12 hrs tea was still very warm ! Definitely recommend it !

Bought this and the black lid is faulty so it leaks. Very dangerous leaking boiling water. This was supposed to be used in my newborns bag for their bottles. Luckily I realised before a serious accident happened. Tried to get a replacement product sent and heard nothing back. Not happy at all. Waste of money and this isn’t a cheap flask.

Very good product. Keeps Hot for long hours

This little flask is brilliant, I'm delighted with it. It holds enough milk for several cups of tea and cereal in work and it keeps it cold. Also the design is very good because you can flip the spout to pour and don't have to fully open the top but is completely leak proof. I would definitely recommend!

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!
