We expect the customer to inspect the part within 30 days of delivery, and if our product needs tweaking, the customer is to notify us in writing. We will rework the part provided that it has not been modified without our authorization, misused, or mishandled. Misuse and mishandling includes, but is not limited to, storage at improper temperatures.
If, at any time an item is to be returned for reworking, the customer should contact Cosmo Optics Inc. to discuss what changes should occur etc.
