HANS Devices on Ebay for an incredible price - too good to be true? After inquiring with HANS, it was found that a company in South America made copies of the devices and was selling them as authentic HANS Devices. When purchasing a HANS, it will ALWAYS have FIA and SFI labels on it and a serial number. The HANS name will be on the back of the device as well. Only a certified HANS will protect you - don't settle for anything less. To ensure you are getting an actual HANS and not a replica, make sure you are purchasing from an authorized HANS Dealer and that the unit is marked and tagged appropriately. Your dealer or HANS Performance products will keep track of the serial numbers so if you want to make sure you have an original, you can verify it.
