I have the non mini version running over months and it has a couple of foibles which are not really complaints as I doubt anyone can do better.
It uses Wifi so if you use in patchy wifi places you will find it not online for a minute or so. But then my phone has wifi issues too.
It turns itself off if varying power input, like a spike.
I wish they made these in UK as I have a few devices I remotely control need the odd power cycle.
