Ok, so I bought this controller almost a year ago and thus far it has been a great controller, but there are some cons with it that outweigh the pros.
Build Quality: 4 out of 5
So this thing feels great, and I'm not talking about the ergonomics. I'm talking about the materials quality. The plastic doesn't feel cheap and the buttons/sticks are all very responsive. The only thing that I have a gripe about are the RB and LB buttons - they have sweet spots that need to be pressed on to get them to trigger. If you're like me and your fingers go all the way across these buttons, hitting the sweet spot can be difficult to get them to actually function. This is the only gripe I have about the buttons on this controller, the rest of them feel amazing and have great response, the D-Pad in particular is great.
Ergonomics Quality: 3 out of 5
This controller is comfortable enough to hold, but it has some issues 'molding' to your hands. It doesn't fit quite right in mine and after a while the controller starts to feel uncomfortable to me in the hands. Everyone has differences though, like I can't stand the way the PS2/3/4 controllers feel in my hands. Get cramps after using them for so long, but everyone else seems to love them... but I digress.
Lighting Quality: 3 out of 5
While the controller's primary purpose is to be held while you look away from it to play your games, it does have RGB lighting built in which is great. The only downside is it isn't as vibrant as the box led me on to believe. It does look good, don't get me wrong, but the colors and intensity of the light are... lacking. It does do what it says though, so there's that.
Longevity Quality: 1 out of 5
So this is the main reason I'm writing this review. I bought this controller to replace a Xbox 360 Afterglow controller for my PC. When this controller worked it was decent enough to use. After not even one year of light use however, the right trigger has stopped working correctly. Sometimes it works, sometimes it doesn't... it's kinda on a 'when it feels like it' basis. And sometimes it even only works halfway even though you have it fully depressed. I could have dealt with it if it were like the back button or the start button, but the right trigger is a little bit important for most games, especially GTA V which was the primary reason this controller was purchased. I've ended up back on my Afterglow controller ultimately, and couldn't be happier.
Overall Quality: 2.5 out of 5
While this controller is very flashy and looks amazing, ultimately you'd be better off buying a Xbox 360 Afterglow controller if you're looking for a great PC controller. If you're buying this for the Xbox One, then you'd ultimately be better off buying an actual Xbox brand controller than you would be getting this thing. I would recommend staying away from this controller, ultimately.
