Does the trick however with minor imperfections
on 24 March 2011
The flask keeps the drink really hot for long periods of time. I always 'pre-heat' the flask with boiling water half an hour before using it, which seems to keep the liquid hotter longer.
The size of the flask is very convenient to be put in a small bag or backpack and taken to with you where you want to go. It contains a generous mug of liquid, which equates to just under four servings using the screw-top mug.
Nothing leaks from the main body of the flask, so it can be put in any position whilst in transit.
After washing the mug, water gets stuck under the seal which is impossible to dry, and a small amount of water can drip from it when being carried.
Mine was very liberally pacakaged (a small piece of bubble wrap inside an unpadded Jiffy bag) and arrived with a dent in the mug.
All-in-all, does a great job of keeping liquid warm, which after all is its main purpose. Useful size, but the cons listed above lose it two stars, as with a name like Thermos you expect perfection.
