1.   Due to the advanced and professional nature of our company's brainwave products and experimental instruments, and in consideration of the curious nature of our customers, we only offer exchanges after sale and do not provide refunds. We accept exchanges within seven days of purchase (customer responsible for return shipping fees). Please double-check before placing an order, and we apologize for any inconvenience.
