You are eligible to exchange your rangefinder for an upgraded model within 60 days from the date you receive the shipment. To qualify for an exchange, returned items must be in their original condition with no evidence of wear-and-tear. All accessories included in the original order must also be returned. All exchanges are inspected upon receipt. This process may take 5-7 business days to complete. If your returned rangefinder does not pass inspection, your exchange will be treated like a return. To start the exchange process, email us at support@blueteesgolf.com. Our customer service support team will either send a return shipping label (for domestic orders) or return shipping instructions (for international orders). Once your rangefinder has been received and inspected, we will send you an electronic invoice for the price difference between the two rangefinders, as well as the cost of the return shipping label (if applicable). Once the invoice is paid, the exchange order will be processed, fulfilled, and shipped.
