How often you use it: once.
Unless your 'house call' bag has one of those, a Cisco blue cable, USB cable, micro USB cable, USB to serial cable, 5 monitor adapter pigtails, ....
My cable collection just continues to grow over the last xx years - someone complained what it weighed when the offered to help carry it once - their guess was it was close to 40 pounds before I put laptop[s] into it.
