We do not accept returns for incorrectly ordered instruments. Please be sure equipment you are purchasing fits your needs.


Inspect your shipment before accepting the delivery and signing any carrier paperwork. It is important to check your equipment for any damage before accepting and signing for delivery. If there is damage to the shipment, refuse it and note the damage on the Bill of Lading or notify UPS/Fedex driver so he may enter the reason for the refusal into the shipment notes.

Please call or email us within 48 hours of receipt, and we will issue a returned goods authorization (RGA) number for the refused shipment. If damage issues arise after signing for the delivery and without first noting the damage on the Bill of Lading or notifying the driver, you will be responsible for filing all claims with the carrier. Therefore, a thorough and immediate inspection of all shipments is a major step before signing for and accepting delivery.


If a reported issue cannot be resolved, you may return your instrument within 30 days. Depending on the item we reserve the right to assess 20% restocking fee.
