All Retra UWT products are included with a minimum of 1 year Retra Warranty. Keeping your Retra Flash up to date with the latest firmware via the Retra UWT App automatically extends your warranty by an additional year to a total of 2 years of warranty. This warranty does not cover any damage caused by misuse, neglect, accidents, abrasion, exposure to extreme temperatures, solvents, acids, corrosion, normal wear and tear or transport damage (by airlines for example). Flooding of the battery compartment is not covered by this warranty. Improper or incorrectly performed maintenance or repairs void this warranty. All repairs or replacements under warranty are free of charge, excluding costs of shipping and import/export duties and charges. We see it as our responsibility to take care of our products even after the warranty period expires. Please contact us if any issues arise with our products at any time.
