Everyone that purchases a HyperVibe Whole Body Vibration Machine, will receive a customer referral code. If you love the HyperVibe Whole Body Vibration Machine, then chances are so will your friends. If you refer a friend to us, and they quote your customer referral number through either the online store, or by phone, we will post you a cheque for $150. Through the HyperVibe referral progam, you can do this as many times as you like, which means refer enough friends and you will have paid nothing for your machine.
