As far as the benefits ..
The downside is as described already often here, the happy times sporadically disconnects from the Wi-Fi which allows the drive through, and then unplug again easily fix.
However, what is for me an absolute Nogo criterion, this is my first stick only about two months was on duty and then re-selling even just less than a month.
This manifests itself in that the stick suddenly constantly off and logs on and no longer connects to.

Well, so long as it works ansich great stick, two times in a row at higher data volumes, however, too expensive for the price and the short life expectancy ..
