The is the 2nd one of these bought here. First one was Nov. 2011 when I bought 20” monitor for my MacBook Pro. Bought along with “6ft 28AWG CL2 Dual Link DVI-D Cable” (item #2408). The casing around the plug on the Mini Displayport plug finally gave up the ghost around Nov. 2017. So, 6 years of everyday use and abuse. The DVI-D cable still rock solid.
