I was close to buying the miaomiao 2, already have the miaomiao 1. But looking in more detail, although it is smaller, the thickness profile is the same. My biggest 'issue' if I can call it that, it the thickness of the device on top of the libre and the miaomiao 2 has the same thickness (7.5mm).
So i'll probably stick with the 1st one. Now with the price drop its a good deal, I bought it initially at $199.
