Absolutely. Its jacket is damaged which means it can now be compromised by moisture which alters the signal properties of the cable. Also looks like it was kinked tightly which can damage it.

That is a switch…look closely it requires power and has lights on it. Its just a 3-port wired gigabit network switch.

Nah look closer - its a switch. USB power supply and normal switch LED indicators on the ports.

Idk why they are marketing it as a “splitter” making it sound inferior…that should make for more painful searches next time I need an actual splitter. Which can be handy for like 2x PoE cameras over 1 existing drop…and even 4K cameras will never saturate 100Mbps so its fine.
