I have the Fullfield E1 shown, just with a different reticle.
My complaint about it is that the objective bell extends further back on the scope than is typical. As a result I can't mount the scope quite as far back in the rings as I would like. I could get Extended rings, but why can't they design the scope to fit in the same manner as everyone else?
Image quality is OK, probably similar to Vortex but it's not a Zeiss.
