4/5 but seemingly the best of what there is to this day.

I'm doing my morning food hot, and fill it into the preheated thermal container. My lunch was always hot so far, so I had to blow yet. Soups I enjoyed 4-5 hours after filling. Fill a rice ladle 3 hours after.

I always make the container to below the lid fully, so not much air stays inside. I can imagine that if only half full, the food then cools faster.

- The minus star comes through the inner lid which has a crack (at the screw so is a kind of shell, and between them is a thin air space), you can not really clean, I sink the whole container actually directly from, and therefore I have not had a problem with fixed-dried food in the gap.

If one missile? The container properly, he also does not leak. He has such a pressure release button, but until now I never had.

I find the reservoir great, and will also buy one for my friend, who are 4/5 ehere a note to the manufacturer nor optimize the inner lid to clean.
