Fixed my issue.
What speedygonzo said. From what I have read some units shipped without any charge and will need charging before you switch on. Some people say at least 45 mins before switching on and the device should start to come to life. (Lights and feedback vibration)
I believe they need an 8 hour charge for a full battery.
