So I've had this controller for about 2 weeks now. I will say I love the back buttons and they are well placed! You can remap in no time without software! However, unlike the back button on PS4, you won't know what they're connected to until you test them. I'd say it's a shame the triggers don't use the adaptive triggers that Sony worked so hard to integrate. The buttons press and stop 3/4 of the way to help you press quickly. I'm also not sure if mine is defective, but my left thumb doesn't always fire for some reason so I can push all the way forward (e.g. a time when it doesn't fire and I just go, meaning, that the controller thinks I'm pushing the grip forward just a little bit.
