Haven't messed around with it to much, so i'll just give a quick review on how it feels. Will update after having used it a few days, see how I feel then but so far it feels stupidly nice.
It felt a little light out of the box but once i added two of the heaviest weights 17g and 14g either side it felt a lot better. I love the PS4 controller, although it isn't perfect but the weight of this just makes it feel a lot nicer in the hand.
It doesn't feel cheaply made either, feels like a real quality product, sticks respond well, buttons have a nice click to them and the back paddles are easy enough to press. I'd say the ones not as far out are a little harder but once i get used to it and muscle memory kicks in they will be fine. I was a little worried about the analogue sticks, but can't complain about them either they move fine and feel really nice definitely an improvement over the standard controllers.
Haven't tried to much just a little bit of BF1 and some MLB 16 but it feels much nicer overall and I feel like my precision is very much improved.
I'd say the only thing which is annoying is it being wired only, but i knew that before buying it and the PS4 is super close to my setup anyway and the cable is 3M so over 9ft and braided so feels super sturdy and it screws into the top of the controller making it very secure.
Check the spoiler for pictures and so on.
So far i'm very happy with it, will give it a few days testing and see how it holds up over multiple games. Also the warranty at 2 years is decent and having bought through Amazon their CS is top notch so any problems and I know i can get it sorted out pretty quickly. Haven't tried the software on PC yet either, will check it out later to see how customizable it is in terms of what can be changed and set etc.
