The 4 player connector is for use with Playstation 2, Connects up to 4 controllers, 8 player action

I was a little wary about buying this initially because I've heard some complaints about the reliability of non official playstation peripherals but I went ahead and bought it because it was a lot cheaper (I also think it's rather tight of sony to only put two controller ports on the console itself). However I've had it for about a year now and it still works fine despite some reasonably harsh treatment. My one gripe is that it's fussy about which ports have controllers in, they all have to be in the right order otherwise it won't work properly. That said it may well be the same with official multitaps, and it's rarely a problem. I'll give it five stars if it makes it to a full two years of use.
