All items I sell are guaranteed from defect, if for any reason the item is not working, I will gladly refund the entire purchase price once the item has been returned. Everything I sell comes from a smoke free home. With the quantity of items sell, it would be impossible for me to be an expert on all items and I do not claim to be an expert on any of the items I sell and may not have knowledge of the functionality of the products which is best left answered by the manufacturer.
