How to Request a Return
Warranty starts from Invoice Date
This warranty offers a combined coverage of 10 years, divided into two phases:
First 5 Years: During this period, you are entitled to a full product replacement in case of any issues or defects. This means if your product malfunctions within the first 5 years, you'll receive a brand-new replacement.
Following 5 Years: After the initial 5 years, the warranty continues for an additional 5 years, but it shifts to covering parts only. In this phase, if any product components need replacement or repair, the warranty will cover the cost of those parts.
This comprehensive warranty (Warranty Method: Return to Sparky Direct) ensures both the longevity and performance of your product, offering you peace of mind for a full decade.
