- Good thermos, keeps warm for a very long time. I poured boiling water in the evening, opened it ten hours later and the tea was still so hot that I had to blow before taking a sip.
- The lid is pressed from two halves, so there is a burr on the seam of the lid, I thought that the burr does not allow the rubber seal to form a perfect circle, so the lid does not twist completely. I removed the sealant, cut off the flash, but nothing changed, later I discovered that the recess for the sealant has a non-uniform width, so the silicone ring sits unevenly. This is a cosmetic flaw, it does not have any effect on the function of the thermos, but from the aesthetic side it does not look very good.
