My brother got this gun roughly a year ago and I've been using it here and there. It is a very nice solid gun that is hard to compete against. It did have a problem with the fuse after a few months of having it, but I easily fixed it by buying a replacement fuse. I've also had problems with the stock mag falling out of not feeding well. We have bought other mags that do not have this problem so I believe it is just the mag that comes with the gun.
Some pros are:
decent rate of fire
good range for an MP5
Some cons are:
Fuse broke (easily replaceable if it happens)
Stock mag has fallen out a couple times in a game.
Stock mag doesn't always feed well.
