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.

Perfect product
Used for 1 week or less
It is a perfect size, can take it anywhere and it also fits wherever I want to put it :) and works just perfect, never leeks and keeps the drink warm for very long time. For me this is "how we do it" !;))
compact size, never leeks, keeps warm long time
Good product.
Used for 1 week or less
I am impressed with these lil things, quality product.
Keeps drinks warm, is easy to clean.
Nothing bad to report.
Used for 2 to 8 weeks
I bought the previous version but salt dropped & cracked the plastic collar. I was delighted to see a new & improved version on sale. When it arrived I realised new & improved means smaller & meaner. Not even big enough to take an average "small coffee". I wish I could just replace the plastic collar from my old one. Hence disappointed!
It works fine
Too small...
