I bought it for my Xiaomi M365 and the fit is perfect, the velcro strips are strong and hold in place (the two vertical ones, for the pole, were a bit long so I ended up cutting them; and the two horizontal ones, for the handle bar, could be a bit longer so the case sits lower and you can have a lower gravity center, but they work just fine).
