Nice and well working. Perfect.
Packaging was not "bullet proof" and the tester arrived a bit damaged - the plastic case is opening a bit. Not a real issue. The tester is ok for basic 1:1 cable testing but rare specific wiring is not tested properly. I did tested it on T-splitter (two 100 Mb lines using 4 wires combined into one 1Gb cable using 8 wires). One line lit up 3 LEDs and the other line does not lit at all.
