Which is better, Xiaomi or Lekou drinking cup?

1. Xiaomi boiled water cup has no heat preservation function, and the hot water will cool for up to 40 minutes, which is inconvenient to use. Lekai water cup has heat preservation function, which can be kept warm for 5 hours in daily use.

2. Compared with ordinary cups and kettles, Lok Kou cups are designed with automatic pressure relief valves, which automatically open to balance the internal and external air pressure. Xiaomi drinking cup has no automatic pressure relief valve design, which will cause water splashing danger.
