The good:
It has a speaker to make gun noises, the box shows they put more effort into the packaging than a lot of companies do. And the gun does look nice.
The bad:
Like most low-quality third-party controllers, this one uses a dongle instead of just using bluetooth. It also uses batteries (of course, not included) instead of using a battery pack or even telling us to get a PSP battery pack for it. It also has no SIXAXIS compatibility. The box claims it's solidly built, to which both I and the person next to me responded "no" when I read it out loud. It feels very cheap. There is a cap to cover the hole where you insert the removable stock, and when the cap is off you can look inside the controller and see all the exposed circuitry. The removable and useless scope is very hard to insert/remove. The trigger is extremely low quality and will probably break with time. Some of the buttons are no where near where your hands will be most of the time.
If they really wanted to make an FPS controller, they should have made something like the FPS Master where the face buttons are moved to the grips. Or the XFPS where they use motion sensing for the right analog stick. Or the SplitFish where they use a mouse for the right analog stick. Overall, this doesn't improve your game at all. In fact, you'll probably play worse with it.
