The device works exactly as advertised. Carrying out a firmware update is extremely easy and can be done on your PC in around 2 minutes. I used it on my PS3 and PS4 and the controller worked great for hours. On PS3, the home button doesn't work, but everything else works as usual. On the PS4, all the buttons worked exactly the same. You must have either a wired controller or a wireless controller with a charging cable attached. It doesn't work wirelessly. Good product.
