Shipping on all ChiroMax products is free for all US based orders. We are currently experiencing a high demand for the v3.0, so it may take us 2-3 days to ship yours out. We ship USPS First Class, and we typically see shipping times ranging from 2-4 business days.
ChiroMax offers a 30 day money back guarantee. If your massage gun wasn't everything you had hoped it would be, send us a message here. We are more than happy to give you an exchange or refund (but we're pretty sure you're going to love your gear!)
