Quality Guaranteed
Backed by comprehensive manufacturer warranty coverage
All products sold by FixGenie come with comprehensive manufacturer warranty protection. We stand behind the quality of every item in our catalog by ensuring they are covered under their respective brand warranties. Warranty periods vary by manufacturer and product type. Most electronic components, computer parts, and accessories include warranty coverage ranging from 12 months to several years, depending on the specific brand and product category. The exact warranty terms and duration are determined by the original manufacturer. When you purchase from us, you receive the same warranty protection as buying directly from the manufacturer. This covers manufacturing defects, component failures, and other issues outlined in the manufacturer's warranty terms. Your warranty period begins from the date of purchase. To make a warranty claim, you can contact the manufacturer directly using the warranty information included with your product, or contact our support team who can assist you with the warranty process. We recommend keeping your order confirmation as proof of purchase for warranty claims. Please note that warranties typically do not cover damage from misuse, accidents, normal wear and tear, or unauthorized modifications. Each manufacturer has specific terms and conditions that apply to their warranty coverage. If you have questions about warranty coverage for a specific product, please contact our UK-based support team before purchasing, and we'll be happy to provide details about the manufacturer's warranty terms.
