Advice to maximise the performance of your isothermal bottle.
Fill the mug with boiling water for 5 minutes. Then replace the water with your beverage. Close the mug. The fuller the mug, the longer the drink remains hot or cold.

Best buy
Used for 2 to 8 weeks
Great mug. Keeps liquids hot for a long time. I bought the black one and this red one was for my son. Great value.
Great flask
Used for 2 to 8 weeks
Really good product which works great best flask I've owned would highly recommend
a brand you can trust
Used for 2 to 8 weeks
The flask keeps water hot for many hours. It looks attractive and very handy. The downside is there are not a lot of sizes or colour you can choose.
A great (slightly over) mug sized thermal cup!
Used for 2 to 8 weeks
This thermal mug holds slightly over a standard sized mug of hot drink. If you warm it before use, as you would with any thermal cup, it will keep your hot drinks hot from morning until afternoon. The teabag holder/ coffee strainer is an interesting feature that I have yet to try out but it also seems to stop any splashes that usually jump out if you drink whilst walking.
I haven't tried it with cold drinks yet but I have no doubt it will perform equally as good!
The size of it is roughly the same as a 500ml bottle of water so it fits into the side pocket of most back packs / day sacks. As it's available in different colours I might just have to get another one!
Very good
Used for 3 to 6 months
Value for money
So good I bought two
Used for More than 1 year
This is great for taking coffee to work or on a shorter walk. Does not stay hot as long as a traditional flask but is fine for travelling or shorter walks. I take mine every day to work in my bike pannier or rucksack. Nice to drink from and robust. Great value - much cheaper than other brands.
leaks with in a week
Used for 1 week or less
I used the mug and was very happy because it keeps the tea hot and no taste changes. But after using for four days now there is leaks of tea and can't even drink from it because of leak. But will give one more try by replacing it.

Not as good as a thermos
Used for 1 week or less
Had some tea out of one of these after walking for 3 hours in freezing temperatures. It was warm but by no means hot. My friend had a proper thermos which still had steam coming off it.
Light and easy to clean
Not as good as a thermos
Response of the brand
Hi, I am sorry to hear that you had issues with the Isothermal 0.4L Mug flask. I am not sure if you aware but before you put your hot drink in, you should put a couple of inches of boiling water in the bottom and leave it for a few minutes. Once it has been a few minutes, you then tip out the water and put your hot drink in.

If you have tried this and you still have the same issue, then please return it to your local store so then they can arrange an exhange or refund for you.
