This is one of the best gaming items I have come across. I'm a casual gamer, with most systems. But I often let my PS4 gather dust because my big hands don't care for double-whammy controllers. So my Xbox One gets the most game time. I have Elite 1 and Elite 2 controllers for my passion for racing games. So low and there I wanted to try Gran Turismo Sport again and just couldn't get in with the double shock. I found this awesome little Brook device to use my Elites on PS4! The controller must be connected for this, but this is not a problem at all. Once I updated the device on my laptop it was easy. Eventually I got used to playing with a controller and almost felt like I was playing on Xbox again! I've tried a few other games and it seems useless. I love it and cannot recommend it more highly! If you think you might need it, just get it! I plan to buy another one for Madness 2 players in the future!
