Query: Failed after 18 months

Did what it was supposed to, but stopped working after 18 months. It wasn't that I was constantly plugging and unplugging cables from it, I simply used it to connect two Ethernet cables and left it alone. (By the way, I have tested both of the cables in question and both still work perfectly.) Very disappointing. I replaced it withTripp Lite N033-001 Modular Coupler Straight RJ45F/F, which is working perfectly so far.
