Warranty Policy

Although we produce extremely durable products, with the lowest defect rate in the industry, we still provide hassle-free warranty coverage.
If a product is defective, and the defects do not include physical damage caused by incorrect or negligent usage, within 365 days of receipt of the product, you may obtain a free replacement from ZKHEAT. To do so, you must contact us (PHYMAT2020@outlook.com) and explain the problem in detail. Most problems with our products are related to incorrect usage and can be resolved with the right suggestion or explanation. If the product appears to have a manufacturing defect, we will ask you to ship it back to us for a free replacement. All ZKHEAT products or accessories with manufacturing defects will be replaced for free. Unlike other companies, we do not charge a restocking fee. If the product you return to us does not appear to be defective or has clearly been damaged by the user, we will ship it back to you at your expense.
