I rate it with one star because it doesn't work for the purpose I bought it for. I wanted an RJ45 cable to split into two RJ45 cables, one for the computer and one for the PlayStation, so that both devices could have internet at the same time. But it doesn't work for this task (only one of the two outputs functions, so I have to unplug and plug the cable each time depending on which device I want to connect). Therefore, it is not a splitter. Luckily, I had an old router that works perfectly for this job (it has four RJ45 outputs, so you can connect four devices simultaneously) and I avoided all this hassle.

It doesn't work. It doesn't split the connection, meaning only one of the two ports works and there is no reason to use it.
