Customer feedback describes setup and everyday use as straightforward, with positive comments on connectivity and perceived value. Speed and signal quality are mixed: some feedback characterises 4G speed and reception favourably, while other reports mention slower performance or weaker-than-expected signal. That matters because the router's claimed Wi-Fi speed does not ensure a strong mobile connection at a particular location.
