Have been using Revenger for more then 6 months now. It's a good mod overall, but still has some cons that i'll be listing;
First and foremost, the front up and down buttons are fairly easy to get pressed while you are carrying it. So you have to lock it always.
Second, the menu is a bit complicated, so you have to check the manual to find the stuff you need.
Given the cons, still the mod is a good looking & modern one.
