Therefore we do not guarantee that the item featured in this listing will be covered by any manufacturer's warranty or support. Some are damaged in shipment. Some of the items we get (because we get such an amazing variety) are things we have no idea how they work, or what they are. This is surplus, excess product.

Ask questions if not completely sure what you are buying. Again: We will only accept a return if we sent you the wrong item.
