Its pros: Great option for 2 channels of communication. Cable + 4g reserve. Works fine, doesn't hang. Set and forget Cons below: No remote monitoring from app on phone. The app only works locally. The price is high

Pros: It works in the Hong Kong region and receives the Internet well in bad conditions on its two antennas. With its cons: The outgoing wi-fi signal could be stronger . But you can fix it yourself if you solder your antenna .

Has pros: Turned on and forgot. The connection quality is good, a convenient "backup" modem. In the country, it also helps out in cases where a regular phone does not catch. Different cons: The antennas somehow twist strangely, it is difficult to put them out so that they do not "fall off".
