CCA Ethernet cables are literally the worst. The wires are much more brittle so it's much easier to break the cable just by bending it a little bit, and since the resistance is significantly higher, they can't go as far as regular pure copper cables, and you can't use them for Power over Ethernet (they'll overheat).
People buy them to save money since they can be a lot cheaper, but often end up having to re-run a lot of the cables in the future. Better to just buy the high quality cables from the beginning. "Buy once, cry once" as the saying goes.
yeah, this is a pretty common issue with CCA cabling, normally this is why people go for things like OFC wire instead, it also carries a little bit more current which is nice.
