HarmonyOS Connect | Smart Temperature Display Titanium Coffee Thermos

This product looks great and feels really nice in hand. It fits perfectly in my bag and doesn’t leak even when tilted or turned upside down. Overall, I’m quite satisfied. I noticed that the temperature display rises gradually rather than showing the heat instantly. When not in direct contact with hot water, it reads about 10 degrees lower than the actual temperature. Initially, I thought it wasn't keeping warm well, but then I realized that after drinking some, when I turned it upside down, the sensor touched the hot water, and the temperature went up by 10 degrees. So, its insulation performance is quite good and can last for half a day. The difference between the displayed and actual temperature could be improved later.

Nice cup, elegant and practical.
