BluAlert Vibrating Bluetooth Wristband

BluAlert has created a vibrating Bluetooth wristband that will alert
you when an incoming call is coming through. BluAlert wants to put an
end to you missing phone calls due to meetings, loud environments
where you can’t hear your phone ring, and those annoying moments when
you can’t actually find your phone even if you can hear it ringing.

And even if the resizable neoprene bracelet is paired with your mobile
phone, it will vibrate if the handset is ever taken more than five
metres away. So you never leave your phone behind again.
