Our industry-leading refund policy allows patients to return their Circadia® device for a refund within 30 days of receipt. If you purchase a device using Klarna financing, you will not be charged a return fee. If you do not use Klarna financing for your purchase, Fisher Wallace must apply a return fee of 10% of the full retail price to cover the cost of medical device processing, and does not refund the cost of shipping. Refund checks are mailed within five weeks following the receipt of an undamaged device.
