Saw this link on Slashdot:
A red digital display counts down the “Study Time Left” and the device beeps and unlocks when the time expires.
The prison-style device weighs 9.5 kg (21 pounds), making it difficult to move while wearing it.
Incentive to study, or S&M toy? You be the judge.
The retailer doesn’t mention it in the ad, but I have to wonder … does it explode if you try to take it off?
