It’s a great sight for those who want to use their PS90 for long-range shooting.

Mounting system may lack flexibility for some users
Some shooters find the 1 MOA center dot too small for quick aiming

The turrets are exposed so they can be easily adjusted by the user, making shots less stressful when you spend your valuable time shooting instead of worrying about alignment errors or other things that could go wrong.
The sight is easy to tune in because it has two dials that can be adjusted quickly and easily. The windage lever sits on one side of your optic, while the elevation is on the top for quick access when needed.
The sight also has a ring around the eyepiece so that you can move it to focus and adjust brightness settings.
My Experience
The red BDC4 reticle is illuminated, but it’s not enough to hunt at night. However, the 12 adjustment levels make up for this shortcoming and allow you greater control over your vision during low-light conditions
the only drawback of this optic is that its adjustment might be a bit hard for beginners. You must be careful while adjusting the turrets.
