How do I return an item?


ALL RETURNS require prior authorization. Any merchandise returned without authorization clearly marked on the outside of the shipping carton will be refused.

To obtain your Return Merchandise Authorization (RMA) number, please contact our Support Center at (860) 276-8796 and have your receipt and invoice number ready when you call. RMA numbers are valid for 14 days from date of issuance. We are unable to accept returns without an RMA number.

To receive a refund or credit, your purchase must be returned with shipping and insurance prepaid, in "as new" condition, in original box and packaging, and with all warranty cards, manuals and accessories. The RMA number must be clearly marked on the outside of the shipping carton. Packages received without an RMA number marked on them will be refused. Any variance from these conditions could result in delay or forfeiture of your refund.

Return period for un-opened items for credit or replacement, at our discretion, is 30 days from date of shipping, except as noted below:

  • Instrument returns (un-opened cartons only) permitted within 14 days from the date of receipt of merchandise, for credit or replacement only, at our discretion, pending inspection.
  • Instrument returns (cartons open upon delivery) found to be defective must be reported to us within 3 days of receipt for possible replacement, at our discretion, pending inspection. After 3 days, the Instrument may be returned to Superior Instrument or the original manufacturer for repair.
  • Software is not returnable.
  • Batteries are NOT returnable for credit or replacement. If a battery is proven to be defective, the original manufacturer's warranty will be enforced. Warranties vary greatly by manufacturer.
  • ALL returns must include original factory box, original factory packaging (foam plastic wrappings, etc.), all instruction booklets and paperwork. Do not deface original factory cartons or packaging in any manner. Superior Instrument will not accept a return if packaging is not in its original condition, or if the item is not packaged properly for shipping.
  • Returns of material that is damaged, scratched, shows obvious signs of use, or has been defaced in any way will not be accepted, and will be returned to the purchaser.
  • All returns must include all the factory accessories which came with the item. No returns will be accepted if any of the originally packaged accessories are missing.
  • Returns must be shipped pre-paid. Superior Instrument will not pay shipping charges for returns. If the item was shipped by Superior Instrument in error, or the item was received defective (not as a result of shipping damage), then Superior Instrument will issue a UPS call tag for return of the item.
  • If any item arrives damaged due to shipping, immediately contact the carrier, have the shipping (tracking) number ready when you call. The tracking number can be found on the shipping label. If the tracking number is not legible, call Superior Instrument at (860) 276-8796.
  • If the carton shows signs of shipping damage, notify the delivery driver PRIOR to accepting the package, make sure the driver makes note of the damage. Keep all shipping cartons, as the carrier may want to inspect them.
  • Refunds or credits, if issued, will not include original shipping and handling charges.
  • Shipping fees will not be refunded if shipment is refused at time of delivery.
  • A Restocking Fee of at least 15% may be assessed based on the circumstances and condition of material returned. This will be determined upon our inspection of the material.
  • Superior Instrument will not accept the return of any item if the UPC code, or other proof of purchase markings have been removed from the packaging, or if the original warranty card is missing.
  • Refunds on purchases made with a credit card will be posted to the original credit card used at the time of sale.
