Oh yes these are vulnerable as by definition we shove them into places where we can't see what's happening to themThe point was when you use them at least twice a week,you’re more likely to snap one if you’re rodding up a cavity …as I’ve done with the super rods ….
I would not usually pull a cable with the rods, generally I pull a draw string in then pull the cable with that. I've has a short flexible rod, maybe 150mm long with every set I've purchased.Fair play. I did once buy a cheapo set from Toolstation. I was feeding coax cable through ceiling voids. I found the cheap cables to be vastly inferior, by that, I mean that the lack of flexibility meant that I had to fashion a wire coat hanger to pull the rigid cable down from the void. I wouldn't have (necessarily) needed to do that with my Super Rods. The floppy bit on the end of the super rods can often be grabbed using the hook included with the kit.
I disliked the cheap kit so much so that when a barman in my local asked to use them to push through the glass washer waste pipe, I told him to keep them.
For it it is worth, I don't have a dog in this "fight". I am tool snob when it comes down to certain tools, eg Festool sanders but not when it comes down to cable rods.
Personally I've found the cheaper rods better, less bulky and certainly easier to use across a suspended ceiling. I've probably managed 15 or 20m which I couldn't have done with more flexibility.
