Latest review is from 2016 and there seems to be a lot of different kinds of issues. Sounds to me like something that is trying to be too many things to too many other devices.
Of course, if you need an SD card reader and/or mobile charger, it’s not that much more expensive than just one of those.
My other question is when it acts as a WiFi network, how are you securing that? I’d be real wary of using it in that capacity other than to just stream content from connected storage.
