Everyone who writes laudatory reviews, just do not understand the issue at all. In fact, this is a plastic box with a very outdated modem (Cat.4) and a Wi-fi module. It is unrealistic to achieve good Internet speed from it. Any not the cheapest smartphone gives a higher speed. The Wi-fi module is also so-so . If you are satisfied with the maximum speed of 10-25 Mbps with a tower in the visibility zone, then take it. By the way, in the same conditions, the iPhone gave out 70-125 Mbps.
