Sounds like a dud $10 Mijia 1A with open button on lid - their lowest end model. Others have button on handle.
I don't know any Xiaomi product with wide spread fitment issues, they're value engineered, but well assembled low-medium end consumer goods. Nice plastic, in Xiaomi white or black, occasionally orange accents. As well assembled as any western kit. Most of their kitchen appliance is some sort of knob and plastic covered button, very easy to clean/maintain.
>consistent design language
Less is more Dieter Ram, white/black, simple geometry with rounded edges, round oled display etc. It's very consistent. Especially considering they make nearly everything, from fridges, to cooktops, washing/dryer, to ACs, heaters, vacuums etc.
Ultimately, they look nice, do the thing they do, for fraction of the price, i.e. affordable / actually make decent design available to masses. Bring "design" to low/medium income markets. Which is core to OG ethos/vision of modernism/functionalism.
