Express Exchange Policy
  • The Express Exchange is an exchange of a failed component for a (usually) rebuilt component that has previously failed and has been repaired, brought up to current revision and subjected to the rigorous testing and QC applied to new units.
  • The Express Exchange provides for the exchange part to be shipped to you before you send in the failed part.
  • The price of the exchange part is a fraction of the cost of a new unit.
  • This low price assumes that the failed part will be returned to us so that we can salvage the parts for future exchange units.
  • There will be no credits issued when you send back the failed part. The credit is built into the price of the exchange.
  • If you do not send the failed part back to us we will send you another invoice for the difference between the Exchange Price and List Price on the part we didn’t receive.
