Once I rented a place with a pretty Xiaomi kettle and I'll never forget how I small ants came out from around the round button in the middle of the lid when I turned it on first time.
I can't say "well designed" if it is just spamming plastic. In this case design or manufacturing defect ended up with big enough gaps in the plastic for insects to enter and all that space under plastic that is impossible to clean. It's a kitchen appliance after all.
The lid button by the way is super inconvenient. You can't just pick up the kettle with a single hand and open lid while you are heading to fill it up. But sure it looks good to some I guess compared to more useful button on the handle a usual kettle has
Never saw any other Xioami kettles since or before. Saw other products though. Didn't notice some sort of consistent design language. Aside from plastic being mostly white maybe? But even that not always true.
I also thought its sensor is faulty because it keeps boiling water for more than 1 minute though maybe that's intentional? Bit later it seemed like metal inside was rusting. But that's more manufacturing than design.
