Not worth it - ZeroTech Optics Vengeance 4-20x50mm Rifle Scope, 30mm Tube, Second Focal Plane (SFP)

I purchased directly from ZeroTech. The reticle wasn’t aligned with the elevation turret, and when adjusting parallax, the reticle would get blurry and appear blue. ZeroTech replaced it promptly with another, and the second one has a black dot randomly in the lower left quadrant that appears to be accidentally etched in the glass. Now when you’re aiming, you see the crosshairs and a random dot in your view at the same time.
