Tpo qulaity hard use Red Dot. Installed on my S&W Pro Series CORE, 5" pistol. I couldn't be more pleased with this setup. Adjustable, clear red dot. Has improved my target aqusition time and allow me to reach out to much greater working distance.
Pros: Robust, Very Easy set up and adjustment
Cons: Battery location- must remove unit to change battery
