At first glance, this is a good quality article. The pourer mechanism is handy job and the cap is sealed shut. The question remains whether this mechanism will be reliable over time. I compared the thermal insulation with a similar product bought 10 euros in hyper-market. I poured in two bottles of water at 40 ° and measured the residual temperature after 24 hours: Result = 29 ° for the "Thermos", 27 ° for the other product. So Thermos slightly better. It is probably difficult to do better with this metallic double wall technology. It's sure it does not replace a good old thermos double-wall glass, more effective to trap calories, but also terribly fragile. So a good buy, good.
