We use air shipping combined with USPS for delivery. For cities in the western United States such as Los Angeles, California, and San Francisco, delivery takes approximately 5 days. For central U.S. regions such as Iowa, Missouri, and Minnesota, delivery takes about 8 days. For eastern U.S. areas including New York, Washington, and Ohio, delivery typically takes around 10 days.
We are confident in the quality of our products, which is why we offer a 3-year warranty. During the warranty period, if you receive a product with quality issues not caused by intentional damage, we adhere to a customer-first service principle and have a policy of replacement only, not repair. We will send you a new, updated product to your address at no additional cost, and you may keep the original product without needing to return it to us.
