Yeah, the Eraticator is quite picky on eyeplacement. More so than the Tasco or Bushnell. Pay attention and it's not a problem, especially for bench or (typically) prone varmint shooting.
You should give Mueller a call, I've seen plenty of posts saying that they're more than willing to talk it over with you and they're apparently pretty good about resolving any problems after the purchase (although I have no experience with this as I have fired about 10 rounds with my Mueller)
