Google Glass is dangerous 'spyware' that harms the privacy of the general public, according to Consumer Watchdog.

The wearable technology went on sale to the public for the first time  on 15 April, however Google has stated that it will only be available for 24 hours and that only those living in the US are eligible to buy a pair.

The device has aroused concern over the security and privacy of users and the public. James Court, president and chairman of Consumer Watrchdog, a California-based non-profit consumer education and advocacy organization, has warned people not to buy the technology.

"This is not just a computer, this is spyware. I'm watching you, watching me. And anywhere you go, with these on, very few Americans will know that they are being recorded," said Court.
