I was adjusting the top piece on my hades and unscrewed it to far it fill into the couch through the crack and has vanished. I have search through the rug and couch for over two hours with no luck. Does anyone know where I can buy a replacement piece have not seen any info online. If there is any other way to make it work with a piece from another device that is out. Any help would be appreciated nothing worse than finally getting something and then after one day you can not use it! Thank you in advance for any helpful comments.
