Does it have inner copper layer ?

Hello, yes, it does. The copper layer lies between two stainless steel layers.

hi, what is the diameter of the 1000ml box? Does the spoon go all the way through to the bottom? Is it good for carrying porridge during travels?

Hi! The diameter is 10cm and yes, the spoon goes all the way through to the bottom so that you can perfectly use it for porridge!

Can I microwave the container?

The electric field strength in the microwave can shift the charges equally distributed in the stainless steel from one end to the other. As a result, the electricity sparks off the edges of the metal. This can break the microwave. You should therefore not put your stainless steel lunch box in the microwave.

I don't understand how it keeps food warm for some people but it doesn't for others?

I don't know. Expectation perhaps? I expect it to come out as hot as it went in if its only 7 hours later. It went in boiling and came out just warm so I had warm soup instead of very hot. My thermos flask for liquids set the standard I expect in all my flasks. My takeaway would be stick to thermos for superior heat retention.
