Yeah they work pretty good! I use this right here.
It's pretty great. I first got it so that I could have more spaces to plug in consoles, now I have it to be lazier! I would reccomend getting an HDMI extension to go with it, that way you don't have to reach behind your tv every time you want to switch consoles.
If you get a long enough extension then you can be like me and just have it sit next to you on the arm of your chair. Then, since the remote undoubtedly fell into the cushions of the seat, you don't have to find it to change inputs, you just click the button on the splitter! Just as a warning, you can't use 4k with this splitter (not that I have a 4k tv anyways!) so you will have to just plug your ps4 pro / xbox one s into the regular tv input!
