Highest end Thermos flask, lowest price I have seen it recently. Usually around £30.

I get that you can just buy a generic flask from somewhere for £10, or even your average Thermos branded one for £15 but not all flasks are created equal.

This is one of, if not THE best flask out there for keeping your hot stuff hot and your cold stuff cold for longer than pretty much any other flask. Perfect for a winter brew when you are out and about.

Looks good but 25 quid for a flask just seems a bit steep
These are good flasks and are worth paying a bit more, but personally I prefer the Life Venture ones. At the moment Cotswold have the Life Venture 1000ml one for only £16 which is a good buy. cotswoldoutdoor.com/p/l…123

I found a £6 that works perfectly. Keeps the drinks really hot for 4-5 hrs. Doesn't leak at all. Sadly it's gone up to a tenner...
only downside being it isn't dishwasher safe but doesn't bother me too much. I have a beer bottle cleaning brush that works perfect in it.

Good tip. Pour in boiling water, drop im a dishwasher tablet, leave for half hr... Gleaming, trust me... Voilà... 😁
Been tempted to get one of these, to see if they're as good as they claim. But i already have 5 stainless steel flasks, of various sizes.

Not a bad price, heat added.
I’ve never used a flask yet that has not sufficiently kept my tea or coffee hot. Cheapest it’s been so granted it’s a hot deal but £25 for a flask is a bit eye popping
£25 is steep but worth it if you need it I have the original version which keeps drinks boiling hot for 12 hours easily.

One of the best purchases I’ve ever made

Probably the best stainless steel flask I have ever used for keeping liquids hot, with the Thermos King coming second. The King already outperformed pretty much everything easily, including Life Venture ones mentioned above. The ultimate is another step above despite being a slightly smaller capacity.

So yes, it's an expensive flask. That's because it's the best flask at keeping your liquid hot for a very long time. 5-6 hours is piffling, you get scalding hot drinks after 12 hours with this properly prepared. Most importantly you can pour and drink half of it, and the rest is still hot hours later. Most generic rubbish is lukewarm a couple hours after one opening.
cheers OP ordered one, used the cheap £10 ones from amazon in the past but they never last. Keep drinks hot but after a few weeks of use they fail to retain heat beyond an hour
Have one and recommended ...
This just looks cool !
How is this for that plasticky taste/smell that you sometimes get from flasks?

Yes, i probably will buy one some time. But i mostly use 500ml size, and i see its almost £30.
If you want your drinks hot for 3-4 hours then get a cheaper one but if you want piping hot drinks after 12 or more hours then get this or the Thermos King
Is this leak proof?
This is an amazing flask. If you need one or thinking of a flask, buy it. Make a brew in this, still be hot after 12 hours. Never had any leak problem with it.
Only problem is that it can be hard to clean.

There are lots of good ways to deep clean a flask, denture tablets, some use dishwasher tablets, but the best stuff I have ever used to get off tea stains is a sachet of something called Thermoclean.

It's not as cheap as other methods, you'll probably pay £5 for only 4 sachets on ebay. But it's amazing stuff and you probably only need use one sachet every few months. Chuck in a sachet, hot water, shake it up a little and leave it overnight. Use a brush on it when the water has cooled if you have any residual left over, but most of the time it just dissolves it all off.

Best one and the cheapest.
Once a week or two
About 25-50ml of cheap tesco/lidl/aldi bleach, top up with boiling water, leave it until stain is gone (1-2h)
Wash in boiling water. Leave it overnight to dry.

Enjoy your shiny, smell free thermos for a long while.
