We take pride in doing quality checks on all our products. All orders are packed and documented with photos before releasing. Thus, we usually know if the item is sent out damaged, faulty or incomplete. However, in cases where the items are sealed inside its packaging or box, we have no way to inspect the contents of the products.As such, The Nest together with The Nest Partner Supplier and the courier service (if applicable) will then conduct an investigation regarding the matter. Your patience and cooperation is highly appreciated in this regard so that we can arrive at a fair conclusion.For items with product warranties, we can easily help you claim the warranty with our The Nest Partner Supplier and have your unit replaced or serviced. Please refer to our Terms and Service under Product Warranty.
