【WATERPROOF LED DISPLAY】 The product uses a waterproof LED display, allowing you to easily read the internal liquid temperature by touching it. (The cup's temperature probe is in the lid. To ensure temperature accuracy, the temperature probe must be in contact with the liquid.) After filling the cup with water, hold it upside down or shake it gently and read the value after 5-10 seconds.

【DURABLE KEEPS HEAT COLD】: The vacuum in cups and mugs can block heat transfer. Our products keep liquid hot for up to 6 hours above 42 °C and cold for up to 5 hours below 10 °C. This is longer than other vacuum flasks. (After 24 hours in 100 °C water, the temperature remains around 40 °C)

【ULTRA CAPACITY BATTERY】: Large capacity lithium battery, the screen automatically turns off when not in use and has a battery life of 2 years. You don't have to worry about changing the battery daily.
