We want you to feel confident in your purchase. If you have any questions or need additional information about our products, please reach out to our customer service team before placing your order. Our knowledgeable staff is here to provide detailed information and assist you in making an informed decision.

In the rare event that your product arrives damaged or defective, please refer to the policies below and contact us for support.

Defect Claims

Products claimed as defective are eligible for replacement only and will not be refunded. Replacements will be provided for the same brand and model only. Each product will be inspected prior to replacement, and the serial/lot number must match the one we shipped to you. You are responsible for return shipping costs, while we will cover the shipping costs for the replacement.

After the claim timeframe has passed, any applicable manufacturer's warranty will apply, and you must pursue the claim directly with the product manufacturer. Please note that replacements are limited to one per item per order.

RMA Number

You must obtain an RMA number within the applicable timeframe for a defect claim. The RMA number should be written on the return shipping label or box. Products returned without an RMA number will not be eligible. RMA numbers are valid for 7 days and the return must be shipped within this timeframe. RMA numbers will not be extended or reissued.
