I had a bug buster on my Prod initially but it would not hold zero. UTG didn't honor the warranty either. I replaced it with a Hawke Vantage 2-7X and it works great. They are about the same price. Hawke Vantage 3-9 is only a few dollars more.
The little Hawke is my only 2-7, my other PCPs wear 4-16, 4-14, 6-24 and a 8-32. I'm thinking of getting the Athlon Talos 3-12, however, to have something smaller and lighter for hunting. I like a simple mil dot reticle for hunting which it has. Vector also has a 3-12 which is almost as light and is significantly shorter. Gets good reviews. But my Athlon Talos 6-24 will focus to less than 10 yards and my Vector 8-32 will not get to 10 yards despite it's rating. The glass on the Athlon is noticably better too. So I will probably get the Athlon. My experience with the higher magnification units isn't directly applicable to 3-12 scopes but the Athlon warranty is better and I like the reticle better too.
