Defective / inaccurate objective bell / poor eyebox / the build & performance do not match the price - Vortex Diamondback 4-12x40 AO Rifle scopes

I give two stars, one for the appearance design, and the other for the reticle design.

I can only imagine whomever is responsible for “this scope’s” performance does not, or has never used a rifle scope that works as it should.
The first sign of trouble came after setting the eyepiece focus I viewed an object at a measured 50 yard distance, adjusted the objective ring to obtain focus, and it was on the 100+ yard marker and it would vary in repeated attempts. I tested this at various magnifications and it varied and sometimes it would come closer which indicates to me I had a bad copy.

The Eye-box performance is totally unforgiving. You have to align your eyes and head exactly in the side to side & fore and aft positions to keep an clean full field of view while set to the medium to upper magnification ranges. This is the kind of trait I would expect in a cheap-o optic that came with a budget rifle in a combo package.

The resettable turrets.... On one of them the hash marks do not align landing them exactly in between.

The build. It’s a nice looking scope. There is a + / - sticker on the fast focus eyepiece that looks like it will roll up or come off any minute. I guess they forgot adding it on the last minute. Everything else is clearly marked. When you turn the objective ring it can be heard like a fine hiss.

I returned the scope for an exchange fr one at the same price point I know will perform for what it is worth or more. A Leupold VARI-X 1 3-9x40 fixed AO.
