After I bought the rig (used but semi-new DOM 2015) it was grounded. I did never jumped on it; never!
  Therefore, it is not possible for me to assess the material.
  The grounded rig was sent to Parachute Systems as fast as possible!
  I think it is not correct that old rigs will bee replaced before my newer one! warranties????
 The delivery time was repeatedly delayed.
 Because false promises about the delivery date I bought no other one.
  Had I never bought this rig!
