Top function, rest "so-so"

Since I am an avid tea drinker, had time ago a container which can hold a long time hot sometimes plus has a good capacity.
I came up with three favorites: Esbit per 1.5 liters, Stanley 1.5 or 2 liter version and this Thermos thermos 1.2L capacity.
As I looked at all three closer I came to the conclusion that the Thermos for my use / better / fancier is more than adequate.

Appearance:
The Esbit (also resembles very much the bottle of Primus) is very bulky and brawny (approximately 1: 1 what size anbetrift, 1.5x wider than Thermos) and acts as if one could so the tents the herring cut into the ground. Similarly, the hammer blow of Stanley gives the impression they would be indestructible. But both fell out because they act for my feeling a little too "military style". However, the grip of the Esbit I find something "beautiful". What stands out in the blue version of the Thermos, is that the bottle a "purple" is down. At first, I sent the first bottle back so, but noticed the replacement that is just so limited. I find it hard on when I hold the bottle to the light and the sun shines on it. At the photo you can see the trick also.
Despite farblicher discrepancies point for Thermos.

Insulation performance:
All three bottles have a very good insulating performance. My test did not extend over several days but about 20 clock pour hot water and drink 10 clock the next day. Subjectively I found the insulation performance of Thermos better than Stanley and Esbit, where I could "feel" a little but better insulation performance at the Esbit.
Here actually draw all men equal.

Durability.
For durability, I can say little at the Stanley and Esbit, but can not imagine that as soon these bottles could destroy anything. The Thermos has in my opinion, hitherto equally good durability and maintains determined so few dents out. However, I notice that the Thermos easily scratch gets. With a usage time of 3.5 weeks, my Thermos has already gotten a lot of paint chips and scratches, which I thought something very "crass" find for the price. The bottle I take with me always and is the bike in my Ortliebtasche. Besides the bottle are there mostly only rain jacket, fleece jacket, gloves, Lunchbox and wallet in it. : - / Well ....
Point for Esbit and Stanley.

Conclusion: So I went on the design, I have taken the thermos, which I would buy now after the experience nevertheless again, because this looks simply beautiful. The insulation performance and the Fassungsvolumnen are really top. The color engraving and rapid scratches should nevertheless be noted.
