Except the same small amount of dead zone on the right analog stick in the PS2 controller has is still presented when you plug in any PS3 or PS4 controller; other than its not a big or small deal

I bet Gam3Gear will release an update that makes the right analog stick not have a natural dead zone.

if you have a modern fight stick then you will love this device very minimum lag and you can use with Ps3/Ps4 controllers wirelessly which is great for long game sessions!
