I used one last year. I just hated worrying about batteries and turning the thing on and off. I kept an extra battery in my vest, but I would wake up and check the gun the night before to make sure it was off. I did kill a good bird with it...so it works. This year, I have put on a regular 1-4x scope. I think I am going to like not having to worry with batteries and off and on switches...but it did cost more than the red dot.
