Simple and very easy to use. It looks bigger in the picture. I connected a large number of different usb modems to it - it finds a connection with all of them. When connecting a 4g modem, he registered the network settings automatically found the connection. Operators of different countries are registered in the settings. Works great in various modes. It consumes very little and is powered by a common micro-usb cable (mini-usb in the picture), but the artery block was not included in the kit. Mico-usb power cable and LAN cable included. Very attractive price ~1.2k.
