Return Policy
Due to the nature of our products, all sales are final and we do not accept returns.
At Zello Labs, quality and product integrity are our highest priorities. Every batch undergoes internal quality control and testing procedures before being released.
In the unlikely event that a product is independently verified to fail stated quality standards, Zello Labs will issue a full refund to the original payment method used for the purchase.
Customers who believe there is an issue with a product should contact us before arranging independent testing so that we can review the situation and assist with the process.
