SIMELO impression Kyoto series welcome thermos 2.0L?

Isn't the brand SIMELO related to elephant seals? I don't care about the products of this brand, but the most valuable thing is after-sales. I bought this pot in Tmall's flagship store in June last year. Not long ago, I found that the heat preservation effect was a bit low. I sent it back for repair. After inspection, the factory told me that it was because the bottom of the pot received a big bulge, which led to the leakage of the vacuum layer and no insulation ... I actually got a new one for free. This service does not mean that big brands are better than big brands!
