Not really. I don't see discotheques or bars buying it. They generally buy the cheapest plastic glass they can find for the former and the later have drink companies offering them free glasses. As for private parties, where your cup is likely to be lost or broken, people won't bring this expensive cups with them.

To me it's more, "lets surf on the Internet of Things". As already said, I don't see the need. Maybe if one day it become as cheap as normal cups. But not now.

Not I saying roofies are not a problem. Just that is not a solution, IMHO.

There are already cheaper solutions to this: http://www.drinkspikedetector.com/howitworks.htm for example.

The website makes no such claim. So no, I don't think the problem of roofies will be solved until certain men learn that sex isn't something you take by force.

Instead, we have a 100 dollar cup that peforms a neat trick.
