Set up was very easy: just press the WPS button on your router and then on this device. I think the signal is a little weak. It fades to one bar in less than 20 ft on the same floor. Nice clean design and seems well made.
The watch has a very sensitive receiver that sets the time every night without having to put the watch by a window as the instructions indicate. The solar cell charges the battery with normal daily activity. The date and day of week panel is very legible. The only negative is how easily the crystal scratches. I don't even know what scratched it but it had a couple of scratches in a few days.
