The alarm clock suitable for couples

This concept alarm clock by Johan Brengesjo (which is interesting enough to add to my collection of different alarm clocks) is an excellent idea for couples that have to get up at different hours and don't want to bother each other with different buzzing alarm clocks.

How? Well, a wireless rubber ring with an integrated vibration device is worn on the finger (the alarm clock has two-user settings and there's one ring for each person). When the alarm "rings" only the corresponding ring vibrates and the person can wake up by sensing the vibration. The light function and the snooze function are engaged by shaking your hand. Move your hand and the snooze gets activated.
