from product page: "Please note! Once this unit is linked with your vehicle it is married to the car by the VIN Number. While you can use it over and over again on your vehicle if needed after a dealer visit, but you cannot use it on another vehicle. Trying to sync it with another vehicle once you paired it with your vehicle can do damage to the item and the ECU in the car. Due to the way the unit is designed to work it cannot be used on another vehicle once it is paired with yours.
Due to this we cannot accept returns for this item in any way. We have no way to tell if the unit was paired or not with a vehicle and if it is returned we cannot use it again. Because of this all sales are final on this unit once you purchase it. There are no returns or exchanges of any kind and all sales are final. Please be sure to ask any questions prior to ordering. Once shipped there are no refunds or exchanges."
Soooo you are charging $500 for software (which costs 0 dollars to duplicate an unlimited number of times) that has some primitive DRM limitations, and claiming that as a basis to not accept returns?
