MILTONSmall Vacuum Flask for Hot Drink 350 ml (12 oz), Stainless Steel Double Walled Insulated Water Bottle for 24 Hour Hot and Cold Drinks, Leak Proof, BPA Free, Food Grade, Thermosteel Flip Lid

Flask bought for use on a Birdwatching trip to Greece. Used to keep hot water to make in cup tea. Having been told at 10pm of a power cut was due the following morning, I filled it with boiling water. 18 hours later, at 4 pm the following day, the water was still hot enough to make a cuppa. Great product, highly recommended.

This is a brilliant flask. I have used it for boiled water for my baby. Used it during night feeds and days out. We was filling it at 8pm and by 8am it was still above 75°c which is very hot enough for a cuppa. Only thing that I'm devastated about is, after 4 months I dropped it and it has a big dint in it and can feel the heat coming through the dint so it's not holding the heat as long as it was but waters still hot! So will be buying another one next week.The bag that it it comes in is lovely and handy.

It smells plastic and sometimes fiddly to close the lid but the taste of the water is fine and keeps drink hot (>70degC) at least 10 hours which is great if you travel with your baby and prepare a formula on the go.

I really like this flask, keeps the tea/coffee very warm for long time, and comes with a nice case.

Best flask I've used.Brought to keep water hot for baby bottles. Lasts 24 and still water is still HOT! Highly recommend

Very disappointed. Used the two of these purchased for the first time this week. All seemed ok until I washed them up. After 2 days the lid (cup) has still not dried out and keeps leeching water. So, water is running down the sides of both the flasks when you put the lid (cup) on. This is because it is a two layer cup and there is obviously ingress between the plastic and the stainless steel. This design fault is on both flasks. I can hear the water inside. So until they dry out, I can't use them again. How useless. Terrible design. Definitely NOT recommended. Unfortunately the return window has closed. Don't waste your money.

We have been using for night feeds and it has changed the game for us. Much cheaper option than the nubby rapid cool etc!

Great quality, love the zipped bags to carry them in. Pouring spouts are good. Drinks stay nice and hot.
