5.0 out of 5 stars Hottest flask yet, well worth the money. 16 Oct 2009
There were so many exultant reviews of this flask that I suspected the Thermos marketing department had been slaving over a hot keyboard. Even so, I ordered the Thermos TherMax Work Series 1.2 litre steel flask: It really does keep drinks hot for a long time, unlike the other two flasks I have had to chuck out.

To test it, I made a flaskful of tea without milk (I added cold milk to the mug when I poured it out, if you are interested). After 3 hours, the tea was as if newly made. After 12 hours, it was as if new tea had just been left cooling in the mug for a couple of minutes i.e. definitely perfectly drinkable and tasty. The difference was barely discernible from the 3-hour-old tea.

After 23 hours, it was just the acceptable side of lukewarm. It was not great but better than other flasks perform after about 4 or 5 hours -- and remember, I had opened the flask a couple of times by then and poured some tea out.

The flask is dear but worth it in my opinion. It will soon pay for itself in terms of motorway service station refreshments abandoned.

The flask must not be immersed in water during washing. It is made in China.

5.0 out of 5 stars Best Flask by far 9 Sep 2007
By Louise
I have used our flask on many occasions, it does exactly what it says. We have used water some 26hours after filling the flask and it still has enough heat to make a hot cuppa (I do recommend pre-heating the flask first). It is also very robust. I wouldn't buy any other flask.

5.0 out of 5 stars Thermos Work Series Stainless Steel Flask 4 May 2009
My husband bought this flask as he was fed up with his tea being cold half-way through the day. He thinks this flask is excellent. Tea stays hot all day long and the flask is very robust. Definitely worth the money.

5.0 out of 5 stars It really is that good 5 Jan 2010
By RH
When I read all of the rave reviews on this flask I thought it would be good. It isn't - it's brilliant.

Even after hours in this cold weather the contents are still too hot to just drink right down.

Quite simply the only flask you should consider.

This flask keeps tea boiling hot for about 8 hours...and warm for over 36 hours!! I would almost say it is too efficient.

5.0 out of 5 stars Super Flask 30 July 2010
This is the best flask I have purchased. I have always had a Thermos and the old one I have is very reliable, however at the end of a full days walking it does start to lose heat. However, the Thermos Work Series 1.2ltr keeps drinks very hot at all times of the day and is well worth the cost.

5.0 out of 5 stars Exceeded My Expectations 25 Mar 2009
By CJ
Amazon Verified Purchase
This is the most efficient flask that I have ever used. Drinks are still hot (not just warm like with other flasks - even from the same manufacturer) hours after filling the flask. On occasion I have not had time to have a drink during the day (so no cooling effect from opening it several times) and on emptying the flask the tea has still been steaming after more than 8 hours. Not the cheapest but you get what you pay for with this one.

This flask kept my hot water so hot I had to add cold water to it 8 hours later! However, it broke within a few months, so I question its durability.
