I've bought one of these a couple of weeks earlier but I've not been able to flash LEDE. I've seen sftp is mandatory. I'll give it a try but last comment says WIFI is messy. I mean I don' car if WIFI is slow but should be stable.
And it's not un LEDE stable (yet) I do prefer a very well supported device.
And no USB so it is very limited (Print server, etc)
