I have the FF reticle on my Elite 3200 1.5x-4.5x-32mm (on my .375H&H Mag.)
During the day, the black reticle is THICK - which I don't really like. During the evening, you take a small flashlight and shine it into the front end of the scope for about 3 min or so. It is very bright in the begining, then gets less bright, and eventually dims out. The total brightness lasts about 20 to 30 minutes.
I still prefer the electric illluminated reticle, but if the batteries go out, then you've got nothing. With the FF, all you need is a small flashlight.
