Brand new, sealed units from our family estate sale.  Originally purchased for a home network expansion project that ended up not happening & stored in a closet since new.  Still in the shrinkwrap they arrived in.  Great way to provide gigabit ethernet thru an rg-6 or rg-11 co-ax cable.  I currently use two of these to link a detached garage workshop/garage to my home network with a 350 ft rg-11 coax and connect at tv, a computer and a security camera all at the same time & it works perfect.  My tv never buffers and my computer downloads are at 200-250Mbs on my Breezeline  cable internet service rated at 300Mbs. There ARE companies offering newer, faster MOCA devices out there - but for much more $$$  If you connect one of these to your existing router or hub via an ethernet cable, then connect via coax to the other unit it just works, no complex setup or programming needed.  Thanks for checking out our sale!
