Alas, this is not the Luntus expected product which keeps the warmth of my morning meal at lunch.
Yet I have followed all the instructions as, heat the metal chamber by pouring boiling water before placing the food or heat up my dishes ...
- After 3 hours, the food is hot enough but begins to cool, so far from being as hot as I had read some reviews before me.
- But after 4 hours in the isothermal bag, food is only lukewarm or see even at room temperature.
Also the compartments are just "laid" on each other, the large metal container and compartments are not interdependent: the bag which when closed keeps all closed, there is no screw system. The metal container is not sealed at all and all the heat is just kept in the cooler bag.
And I thought to have found an alternative to the famous Thermos exorbitant price, I'm pretty disappointed with this purchase.
