Mueller has done a great job on the engineering and QA for this scope. I've owned Leopolds and Nikons in the $450-650 price range. None match the magnification range of the Eraticator, and construction, quality of optics and zero stability are easily on par. Unbeatable value for the $.
My only wish is for reticle options beyond the most basic unmarked crosshairs. If you need monster magnification and clarity but are depending on your scope for range estimation, you'll need a different (and more expensive) unit.
Pros: Monster magnification, bright and clear optics, stable zero
Cons: Basic reticle
