  • If an item fails within the first year of the warranty period, Masterclock will pay for shipping costs to return the item to our location via a pre-paid shipping label and ship the repaired item back to you.
  • If an item fails after the first year while under warranty, you are responsible for associated shipping costs.
  • If an item is outside the warranty period and requires repair we will inspect, repair and return the item to you for a reasonable charge for the work and the cost for return shipping.
  • If you think an item or system is not working properly we expect you to read the instruction manual, talk to our customer service department and make a reasonable effort to resolve the problem.
  • If you return an item to us for repair "because it doesn't work" and the item is found to work properly, then we will charge you an "Analysis/Inspection" fee plus the associated shipping costs.
  • The above RMA request forms and RMA policies and procedures are intended to clarify rules, prevent misunderstanding, and expedite the resolution of any issues.
  • Any returned merchandise must be packed in the original shipping container and packing material complete with all instruction booklets and accessories, be free of any blemishes, and show no signs of damage.

After 30 days, all sales are final.
