Once the product is received, we'll test it and then send you a replacement within 1-7 days after receiving the defective product. You'll receive another e-mail confirmation once the replacement is sent. With such a low margin, those who experience defective products have to share the cost. Otherwise, the cost has to be spread across board, leaving only higher prices for all. We do pay for UPS Ground to ship replacement items back to customers.
Customers are responsible for any shipping upgrades.
To be sure, we have to pay the shipping of ALL defective products back to our venders. We would like to distribute products with the lowest return rates possible. For the same reason, we publish return rates of certain products on our web site to encourage customers to purchase only reliable products with low failure rates. There is just no way for us to tell if and when a product is or becomes defective without testing it. Unfortunately, we cannot test all products before shipping.
