I purchased eight. Four were 2 1/-16X and four were 4 1/2-30X. The first 4 1/2-30 was returned for warrantee and then returned to Bushnell for a refund. The other three are great. All the 2 1/2-16X glass was not as clear as the 4 1/2-30 so they were sold with that explanation.
All of the ones I mounted has the reticle move exactly the amount indicated on the turret.
