Vibrating Bluetooth Bracelet

Every wonder how far you can take Bluetooth technology? There are the headsets, the connectors, and pretty much everything else.
Now there is a Vibrating Bluetooth Bracelet, which will signal you on the wrist when you have a call on the cell phone in your pocket. I suppose the cell phone could be elsewhere, provided the phone is within range. I don't really know the range, and I have no idea how effective the vibration is.
Still, we could always use another reminder when we miss a call. I have to admit, it has a nice look for about $49.
