DVI Extender, MOERISICAL 197ft DVI Extender Over Single Cat5e Cat6 Ethernet Cable Support 1080P (up to 60M, Transmitter + Receiver) (60M/197FT, Transmitter + Receiver)

I recently purchased two of these units for my job. When we tested them neither of the units were functional, even with short lengths of cat 5e cable. We were frustrated at first because we thought that the units did not work as intended but then we looked at the box and realized that it said "DVI Extedner" not "DVI Extender". However, the unit does not work as an "ex-Ted-ner" either as we still have Teds running all over the place.
