We bought 16 pcs of these drums. First of all, it was random what side the display/source plug was on the drum. Second, the cap on the plugs fall of.
We use these as a rental company, to avoid too many sdi/hdmi converters on 50m stretches. Out of the 16 we bought a year ago, (out maybe 2-3 times a month) only 2 are still in working condition, and even those two are unreliable.
