Ok, I own a cocker with a 4500 Armageddon, and in the 7 months I have had it, I have had no problems with it
My gun chronys fine, always consistent and it is easy to adjust the settings (3/32 size allen key)
A few of my teamates own max flo`s, they too have found them very good, obviously the max flo has advantages over the armie (self regulating + it can run on co2 or air), but.......the unit with cradle is larger than the armie
And finally AA, this is a very nice air system, but IMHO you really dont need it on a cocker.....get the armie, you wont be disappointed
