Most part of the Wi-Fi detectors are already incorporated in a device, like a notebook or cellphone, but this gadget is different.

Like the name suggests, the Wi-Fi watch displays information about the wireless signal strength, which can go from 0 to 8. So the next time you are in a public place and want to know if the wi-fi signal is good enough to surf the net, instead of taking your laptop out of the case, turning it on, and so on, just press a button on the watch and wait for the result.

The Wi-Fi Detecting Watch also has other features (alarm, countdown timer) and is well styled with steel case and rubber strap band.

It costs $30.
