If you feel embarrassing to wearing the WiFi detector T-shirt in order to check for a restaurant’s WiFi signal, maybe you should think about this WiFi watch that is also have the same functionality.
Frankly, this WiFi watch is not good in the design. I think most of the people will probably ignore it if it is without the WiFi detector feature. But I doubt people will like it. Now there are more and more cell phones has the abilities to connect to WiFi, this watch will completely outdated.
However, it is quite easy to detect the strength of local WiFi connections with a touch of button, so you can select the best location from which to hook up for your laptop.
