Both sound useful.
My Ethernet is exposed patch cords and a few custom cables, so easy to troubleshoot/swap out. I can continue to trust Ethernet blindly until I have in-wall segments and wall plate connectors (next house?) that may require confirmation that they are ok and not the problem. But, being able to test custom Ethernet cables may save me some grief, if I ever make some more.
I'm adding MoCA 2.5 backhauls over existing in-wall RG59 coax and would like to prove a coax segment ok before I hook it up and hope for the best. And if the tool can confirm 2.5Gbps capacity, that would be nice to know provided that tool doesn't cost an arm and a leg.
I suspect I'm like a lot of people when it comes to such tools... live without them until some theshold need or justification... like confirming my existing in-wall coax is suitable for MoCA 2.5 networking.
Confirming in-wall telephone wiring would be useful, too, for use with ATAs.
