For £6.99 you get 10 x 1m glass-fibre reinforced rods for feeding cables through conduits or hollow walls. They screw together, and there's also a hook adapter, a flexible piece and a small adaptor with a slot in it. I've always wanted to feed a Cat-5/6 cable through my upstairs walls, because the network is much faster than with TP-Link plugs which I currently use in remote parts of the house.
They were one of Aldi's Specials from last Sunday and yesterday Aldi in Spalding still had lots available. But they will all go soon. They appear to be of good quality, with brass threaded connectors at each end.
