The common sense of coffee utensils to distinguish between true and false Tiamo mocha pots

Today, when I went to sit with a friend, I saw that he also used a Tiamo mocha kettle, which was the same model as mine. I always felt that it was a little different from mine, so good letter used a Vernier caliper to measure the thickness of the stainless steel wall of the mocha pot, about 0.5mm, weighing 670g. Back home to measure mine again, the thickness is 1.2mm and the weight is 760g. It seems that no matter how difficult it is to distinguish the appearance of counterfeit goods, there are still differences in data. When there is a tx that needs to buy a Tiamo mocha pot, you might as well ask the seller the thickness and weight of the pot.
