A great product at its price point, I bought two of these to run 8 channel adat audio from a Tascam DM 24, in my studio, to a RME hammerfall sound card that lives in my computer in a different room, more than 6 years ago.
The cable comes with good quality metal terminals at either end and handy little rubber caps to protect the glass ends when not plugged in to anything.
Having given these cables some fairly heavy use over the years (mainly plugging and unplugging them) they still work without fail.
I would highly recommend these to anybody that needs long adat cables in their lives
