Things I liked: Easy to adjust windage and elevation, once set... it was spot on accurate, kudos for the new .177 Magnum Research Desert Eagle on which it was mounted.
What others should know: So, it's new and it could just be me, but... I sighted it in with the reticle set to the small dot. I was shooting about 10 yards at a quarter size bulls eye. Once it was set all shots were in the bulls eye. I was amazed. Then I switched to a different reticle and shots were grouped about an inch to the left... changed back to the small dot reticle and still off to the left. I will continue to play with it and see if it was just me. But I'm a little shy of changing to another reticle as it is currently so accurate and I don't want to mess with it.
