I used the reflex when they first came out, only thing I still like about them is they don't require batteries. It was prone to washing out the triangle in really intense sunlight, so I got the polarizing light filter for it, and although it solved the bright light issue, it was really more trouble than it was worth to keep track of it when it had to come off for lower light use. I wouldnt spend the money for one now with the small price difference between the reflex and the new generation aimpoint with the extended battery life. Not that it matters much, but I remember that reflex sight being so large that it looked like a dog house was parked on top of the rifle.
